New Businesses

Adenios, Inc.

  1. Adenios, Inc. can precisely control the blood-brain barrier to improve the delivery and extend the patent life of existing drugs for brain-cancer, Alzheimer's, MS, Parkinson's, and other diseases. While the blood-brain barrier is a critical component of the central nervous system that prevents toxic substances from entering the brain, it also prevents over 98% of existing drugs from being delivered to the brain. Adenios is developing mechanisms to modulate blood-brain barrier permeability that both allow and prevent small-molecule, antibodies, and cells from entering the brain.

ADispell, Inc.

  1. ADispell, Inc. is dedicated to discovery of drugs for treatment and prevention of Alzheimer's Disease (AD), currently a disease without a cure. ADispell research has revealed a novel mechanism that explains AD onset and has discovered lead compounds that interact with that mechanism in a way that has potential to halt AD advancement. The Company has performed successful in vitro work and has a scientific plan to make this technology attractive to the pharmaceutical industry.

Coferon, Inc.

  1. Coferon, Inc., a company based on technology from Weill Cornell Medical College, is developing a platform for making a new type of drug to reach targets that cannot be modulated by current drug technologies. Today's approved drugs are limited in their ability to reach drug targets inside the cell, in part, because of the size of the drug molecules. The vision of the Coferon platform is to develop orally active drugs that act like small drug molecules, can permeate cell membranes, and once inside, can assemble into larger molecules to behave more like biologics.

Ezra Pharmaceutical, Inc.

  1. Ezra Pharmaceutical, Inc., is a company based on technology from Weill Cornell Medical College and is currently developing a first-ever preventative therapy for diabetes-related blindness. Also, known as diabetic retinopathy, this disease is the leading cause of adult blindness in the United States and the developed world. This breakthrough technology utilizes the concept of a "therapeutic switch" which is the reformulation and repurposing of an already approved FDA drug for a new indication.

Hybrid Silica Technologies, Inc. (HST)

  1. Hybrid Silica Technologies, Inc. (HST) develops nano-structured silica materials, with a current emphasis on fluorescent core-shell nanoparticles for imaging, diagnostics, and sensing. These advanced materials have applications in life sciences, consumer, energy and electronics industries. HST's materials are based on amorphous silica, a highly versatile, thermally stable and "green" material.

Novomer, Inc.

  1. Novomer, Inc., a company founded on novel catalytic technologies, is developing "green" polymers, including plastics that are biodegradable and use carbon dioxide as their base ingredient. Most plastics are produced using petroleum products as the primary source of carbon. Producing plastic from petroleum harms the environment since petroleum comes from underground oil reserves that release large amounts of carbon dioxide into the air when processed. When plastics are disposed of, petroleum-based plastics do not biodegrade and produce more carbon dioxide, an environmentally harmful greenhouse gas that has been attributed as one of the key causes of global warming. Due to the fact that Novomer's plastic-making process actually consumes carbon dioxide, Novomer's "green" plastics may lend support to the recent trend for a "second plastics revolution."

Orthogonal, Inc.

  1. Orthogonal, Inc. is exploiting a novel, patent-pending photoresist and process to manufacture organic electronics using the standard electronics manufacturing technology, photolithography. In creating this process, organic electronic production can leverage current production facilities unlike other organic electronic manufacturers. The initial focus of the company is to produce organic light emitting diodes (OLEDs), to compete with LCDs, for the $100 billion display market.

Reparo Therapy, Inc.

  1. Reparo Therapy, Inc. is a Weill Cornell Medical College start-up developing DNA repair enhancing consumer and clinical ingredients and products. These include DNA repair enhancing cream that treats sunburn and prevents skin cancer, DNA repair enhancing nasal spray for lung cancer prevention, and DNA repair enhancing anti-aging cosmeceuticals.

Veratag, LLC

  1. Veratag, LLC is commercializing a new type of security technology that is simple, cost effective and highly secure for use in RFID, lock and key, and other applications for identification, authentication, and anti-counterfeiting.

Agriculture & Plant Varieties

Acyl Sugar Tomatoes for Insect Resistance

  1. Martha Mutschler-Chu
    Plant Breeding & Genetics, Cornell University

    Insect feeding results in direct crop loss, as well as, transmission of viruses affecting yield and quality. Acylsugars on plant surfaces correlate with resistance to pest infestation. These tomato lines exhibit high level expression of acylsugars, robustly reducing pest infestation and virus infection.

    Chunhui Xiang
    Fiber Science & Apparel Design, Cornell University

    This technology offers a new method to deliver and time the release of pesticides and related compounds in agricultural and non-agricultural settings. Fibers are produced from a blend of biodegradable polymers and then formed into a non-woven fabric. The chemicals are then delivered in a timed release fashion by diffusion of the chemical from the fibers during biodegradation. The rate of biodegradation of the fibers can be controlled by the choice of polymers. The fibers can also be used to form films, pellets, capsules, and other plastic shapes.

New Cornell Red Apples: Crisp, Sweet, and Tart

  1. Susan Brown
    Horticultural Sciences, Cornell University
    Kevin Maloney
    Horticultural Sciences, Cornell University

    Two new Cornell apple trees produce attractive glossy red apples. Their fruits are crisp, juicy and firm. One produces fruits that are very sweet. The second one produces fruits with a good balance of sweetness and tartness - slightly more tart than sweet. Both trees are productive and the fruit has long storage and shelf life.

Soy-Based Fibers and Fibrous Structures for Bioremediation and Pest Management

  1. Michael Hoffmann
    Entomology, Cornell University
    Jeffrey Gardner
    Entomology, Cornell University
    Anil Netravali
    Fiber Science & Apparel Design, Cornell University

    This green technology is for a fibrous pest deterrent that can be sprayed on-site and expedite bioremediation by reducing erosion, improving seedling establishment, enhancing soil properties, and protecting emerging vegetation from pests It provides both a mechanical and chemical barrier, coating plants, animals, or structures and physically preventing the infestation of unwanted pests. The fibers may be allowed to decay on site since they are biodegradable. As they degrade, they provide necessary nutrients to the growing seedlings/plants and eliminate the need for synthetic fertilizers. Plastic-based fibers were previously demonstrated to protect crops from pests however those fibers are difficult to produce on-site and are non-degradable. The present invention provides advantages over plastic fibers in that they are biodegradable eco-friendly and use sustainable, green materials.


Altering Plant Cell Wall Structure for Cellulosic Ethanol Production

  1. Jocelyn Rose
    Plant Biology, Cornell University
    Carmen Catala
    Plant Biology, Cornell University

    This invention can be used to alter the characteristics of plant cell walls, making them more amendable to break down for conversion to biomass. Currently, limitations exist for the use of biomass as a biofuel, mainly in the hydrolysis (chemical process of cleaving a molecule into two parts with the addition of a water molecule) step of the process. Hydrolysis of cellulose is critically important in the carbon cycle but is now recognized as a key limiting step in breaking down cellulose in plants to access the sugars for fermentation for biofuel production. The altered cell wall structure would create plants with better characteristics for bioprocessing and are better candidates for biofuel production.

Improved Production of Proteins in Plant Chloroplasts

  1. Maureen Hanson
    Molecular Biology & Genetics, Cornell University
    Beth Ahner
    Biological & Environmental Engineering, Cornell University

    Applications for this technology are two-fold. First it provides a mechanism to enhance the protein production of foreign proteins in plants. There are economic advantages to using plant based protein production versus micro-organisms in that (i) plants use solar energy directly rather than reliance on other energy feedstock; and (ii) increasing protein production from plants only requires planting and harvesting more seed, whereas scale-up of microbial systems requires more capital investment in equipment and maintenance costs. Secondly, the gene examined here when over-expressed can be extracted from the leaves of a plant as a source of enzymes for cellulose hydrolysis, a step in cellulosic ethanol production that has been limited by both cost and efficacy. Using plants to express high levels of these enzymes will be both an efficient and cost effective means for generating enzymes to process cellulosic materials for biofuel.

Methods to Improve Alcohol Tolerance in Microorganisms for More Efficient Ethanol Production

  1. Manuel Villa
    Molecular Biology & Genetics, Cornell University
    Susan Henry
    Molecular Biology & Genetics, Cornell University
    Larry Walker
    Biological & Environmental Engineering, Cornell University

    One of the main concerns of the ethanol production industry is the maximum concentration of ethanol that yeast or other microorganisms can tolerate during fermentation while remaining viable and productive. This new invention can be used to modify cell membrane structure in yeast and fungi to improve survival rate during ethanol production. By knocking out a single gene, the yeast exhibits a higher tolerance to exogenous ethanol. Increasing the terminal ethanol concentration in a fermentation from 5% to 14% can reduce the distillation energy cost by 50%. This invention is useful for the ethanol production industry to achieve a higher terminal ethanol concentration in fermentation and hence to reduce distillation energy cost.


Anti-Addiction Vaccines

    Despite decades of effort, there are no small molecules, monoclonal antibodies, enzymes nor active vaccines approved for treatment of cocaine addiction. The major hurdle is that addictive drugs, like most small molecules, are poor immunogens. Attempts to link cocaine analogs to larger molecules, usually proteins, have had limited success. A new technology linking a cocaine analogue to the proteins of a disrupted adenovirus has been developed. Using cocaine and nicotine as the examples, these anti-addiction vaccines elicit high level, high affinity addictive drug-specific antibodies sufficient to reduce drug-induced locomotor activity in animal models.

Branched Chain Fatty Acids for Prevention and Treatment of Gastrointestinal Disorders

  1. Tom Brenna
    Nutritional Sciences, Cornell University
    Rinat Ran-ressler
    Nutritional Sciences, Cornell University

    This technology provides a method to treat and prevent necrotizing enterocolitis (NEC) in premature babies by orally administering branched chain fatty acids (BCFA). NEC, a life-threatening condition that affects 8-10% of premature infants, is caused by an overabundance of pathological bacteria in the gut. BCFA is possibly a necessary factor for normal gut development and an enhancer for the growth of gut friendly bacteria. Because BCFA are endogenous compounds, products derived from this technology will have few side effects, rendering this technology safe and low risk for all age groups. BCFA can also be included in therapeutics for conditions that involve microfloral colonization of the gastrointestinal tract, e.g., maintain a healthy gut while on or after antibiotic treatments and to treat inflammatory conditions involving the intestine, such as Inflammatory Bowel Disease (IBD).

Commercial Platform for Dependable Predictive Biomarker Model Development and Evaluation

  1. Fabien Campagne
    Physiology, Weill Cornell Medical College

    The development of reliable biomarker models from high-throughput data is a prerequisite to fully realize the benefit of personalized medicine. This invention teaches a novel approximation of feature selection error, in combination with biomarker modeling factors (BMF), to calibrate performance estimates. This BMF calibration approach can facilitate the identification of reliable and dependable biomarker models and may be effective in other domains where models are developed with few training samples and large numbers of features.

Establishing New Standard of Care in Anesthesia

  1. John Savarese
    Anesthesiology, Weill Cornell Medical College

    Neuromuscular blocking drugs are used clinically as adjuncts to anesthesia to induce paralysis, so that surgery can be conducted with fewer complications. Because these drugs can also cause paralysis of the diaphragm, tracheal intubation and mechanical respiration is typically required when neuromuscular blocking drugs are used during surgery. When surgery is complete, there is generally no medical reason to continue the blockade, but the drugs can take a significant period of time for their effects to cease. A series of novel neuromuscular blocking drugs that have a specific duration of action which can also be reversed using a proprietary antagonist, thereby significantly reducing the patient's post-surgery recovery time have been developed. The ability for the anesthesiologist to do this adds a significant safety factor to the wake-up process at the end of anesthesia and surgery.

IL-4 Fusion Proteins for Superior Monoclonal Antibody Production

  1. Bettina Wagner
    Population Medicine & Diagnostic Sciences, Cornell University

    The IL-4 fusion protein system provides a simple and superior method of eliciting a robust immune response to proteins in their native form. Potential applications include development of monoclonal antibodies for therapeutics, diagnostics or superior research reagents. Antigens against which good antibodies have proven difficult to develop have been successfully developed and characterized.

Integration of RNAi and Protein Knockout Technology for Efficient Eradication of Cellular Proteins

  1. Pengbo Zhou
    Pathology, Weill Cornell Medical College

    The ubiquitin-proteasome pathway is a major proteolytic machinery that selectively destroys cellular proteins. The "protein knockout" technology has been developed that harnesses the SCF ubiquitination machinery to direct the degradation of otherwise stable proteins. While protein knockout and RNAi are both aimed toward reducing or eliminating the levels of desired cellular targets, the two technologies differ mechanistically in that protein knockout operates at the posttranslational level to directly destroy the target protein, while RNAi functions to block the biosynthesis of the protein of interest. Recent studies exploited the complimentary properties of RNAi and protein knockout for more efficient eradication of stable cellular proteins with potential translation into a novel therapeutic strategy for disease intervention.

Method for Monitoring the Heart to Prevent Ventricular Fibrillation (VF) - the Most Common Cause of Sudden Cardiac Death

  1. Robert Gilmour
    Biomedical Sciences, Cornell University
    Mark Riccio
    Biomedical Sciences, Cornell University

    Pharmacological approaches for preventing VF have been largely unsuccessful due to an inability to reliably predict VF for the timely treatment. This is evidenced by the fact that VF is the major cause of the 335,000 sudden cardiac deaths annually in the US alone. A new stimulation protocol to induce VF in adult beagle dogs that closely approximates the clinical situation in human has been validated. Based on this protocol, a computer model has been developed for incorporation into implantable devices to monitor the heart for electrical activity that is predictive of VF onset and hence enabling timely pharmacological intervention.

Method to Attenuate IgE-induced Release of Histamine

  1. Andrea Cerutti
    Pathology, Weill Cornell Medical College
    Kang Chen
    Pathology, Weill Cornell Medical College

    Despite the current knowledge of allergic reactions, the prevalence of allergic diseases continues to increase. In some areas of the industrialized world, up to 50% of the population is affected. New functions of immunoglobulin IgD have been discovered. The discovery can be exploited to develop non anti-histamine allergy drugs that attenuate IgE-induced histamine release and to screen for novel antimicrobial agents.

Powering Bio-Nano-Machines

  1. Alexander Travis
    Reproductive Biology, Cornell University

    The energy producing system in the tail of sperm has been harnessed by attaching the enzymes involved in converting glucose into ATP onto chips. These chips can be incorporated into bio-nano-machines (nanomachines whose component parts are comprised of biological material) to provide the necessary energy source for their power - one of the key obstacles to their development. Bio-nano-machines hold much promise and could potentially revolutionize the medical industry by performing mechanical operations, inspections, and treatments of disease all inside the body to achieving ultra-high accuracy and localization in drug delivery.

Tissue-engineered Spinal Disc Replacement

    Mechanical & Aerospace Engineering, Cornell University
    Robert Bowles
    Biomedical Engineering, Cornell University
    Roger Hartl
    Neurological Surgery, Weill Cornell Medical College
    Harry Gebhard
    Neurological Surgery, Weill Cornell Medical College

    This invention describes a tissue-engineered intervertebral disc that mimics the native biological disc and can be used for spinal disc replacement. Unlike current solutions, which use metal and plastic implants or merely attempt to repair damaged discs, this disc is formed through a self-assembly process of collagen gel and collagen fibrils. With tests showing good toleration of the discs in animals (no signs of inflammation or foreign body response), the technology holds great promise for treatment of spinal disorders.

Ultrasound Assisted Brain Drug Delivery Needle

  1. George Lewis
    Biomedical Engineering, Cornell University

    In traditional convection enhanced delivery (CED), drugs are infused locally into tissue through a cannula inserted into the brain. Transport of the infused material is dominated by convection, which enhances drug penetration into tissue compared with diffusion delivery. This current invention uses a pocket-size portable ultrasound system to provide enhanced delivery (UCED) to the brain.


Alkaline Electrolytes for Better Fuel Cells

  1. Geoffrey Coates
    Chemistry & Chemical Biology, Cornell University
    Henry Kostalik
    Chemistry & Chemical Biology, Cornell University

    This invention provides novel thin films useful as anion exchange members for fuel cells. The resulting alkaline anion exchange membranes offer reduced methanol crossover and greatly enhanced electrokinetics. Further, these membranes permit the use of cheaper, non-noble metal catalysts and thus allowing the cost of fuel cells to be significantly reduced. This technology holds promise in expanding the utility of fuel cells.

Safe Electrolytes for Li-Metal Batteries

  1. Lynden Archer
    Chemical & Biomolecular Engineering, Cornell University

    A new class of star-branched hybrid polymer electrolytes has been developed for high capacity, faster recharging, lithium-metal batteries. Despite their much higher ionic conductivities, the electrolytes offer comparable thermal stability, improved mechanical strength, and similar levels of chemical stability towards metallic lithium, as currently used solid polymer electrolytes.

Information Technology

A Private Overlay for Cellular Networks

  1. Stephen Wicker
    Electrical & Computer Engineering, Cornell University

    Cellular telephony is a surveillance technology. Cellular networks were designed, however unintentionally, to collect personal data, thus creating an extremely attractive source of information for law enforcement agencies and marketers. The impact of this surveillance on the users and uses of the cellular platform is becoming increasingly important, as the platform plays a prominent role in social, economic and political contexts. It is possible, however, to secure cellular networks against surveillance. This invention is a private overlay for cellular systems that protects user privacy by strictly separating equipment identity from user identity with the addition of a Public Key Infrastructure and Certification Authority (PKI).

Bucky-balls Give Flash Memory a Boost

  1. Edwin Kan
    Electrical & Computer Engineering, Cornell University

    Molecular engineering and the use of C60, or bucky-ball, in memory applications can greatly improve performance. While various solutions, including metal nanocrystals, have been proposed for the expansion of flash memory, issues such as run to run reproducibility have prevented wide acceptance. This technology takes advantage of bucky-ball's tunable properties and well-defined molecular orbitals to prompt resonant tunneling through SiO2 at high fields. The result is greatly improved nonvolatile memory with a program/erase time ratio more than an order of magnitude better than current solutions. The technology provides a practical way of expanding memory applications.

Compilation Framework for Continuous Query Processing

  1. Christoph Koch
    Computer Science, Cornell University
    Yanif Ahmad
    Computer Science, Cornell University

    This invention uses aggressive compilation techniques to turn database queries into lean, highly-tuned query processors. The techniques produce code that incrementally maintains query results and which are particularly well suited for stream processing applications such as high-frequency algorithmic trading and for online data warehousing. This invention provides game-changing efficiency improvements of four orders of magnitude and more in these domains.

Search Engine Ads: A New Auction Software System for Selling Ad Space

  1. David Martin
    Computer Science, Cornell University
    Johannes Gehrke
    Computer Science, Cornell University
    Joseph Halpern
    Computer Science, Cornell University

    Search engine advertising space is currently sold through an auction process. An ad yields payments to a search engine only when a consumer 'clicks' on the ad. This invention provides a system and method that supports an enhanced bidding process with very fast bid-winner determination. Instead of only allowing bids to be based solely on clicks, the invention includes algorithms to provide more bidding features which include clicks, purchases, and the ability to bid on various slot positions on a search results page. This more expressive approach to bidding provides better flexibility to advertisers, and more ad revenue potential for search engines.


Monolithic Nanoparticle Filters

    Fiber Science & Apparel Design, Cornell University
    Huaning Zhu
    Fiber Science & Apparel Design, Cornell University

    This method to fabricate polypropylene (PP) monolith filters contains an array of micron-sized channels. The filters have consistently sized and spaced nanometer-scale pores for chemical and virus protection. The main advantage of this new method over existing procedures, such as nuclear track-etch membranes, is its capability to precisely determine the distribution pattern and shape structure of the channels in the porous polymer film. This technology has applications in the defense industry.

Patterning of Nano- and Micro-Arrays of Biomolecules and Cells Using a Polymer Stencil

  1. Harold Craighead
    Applied & Engineering Physics, Cornell University
    David Lin
    Biomedical Sciences, Cornell University
    Christine Tan
    Biomedical Engineering, Cornell University

    This invention is a high-throughput method to generate microarrays by the combination of aligned printing with a polymer template. The polymer is first deposited on a substrate and then pre-patterned with openings using standard lithography methods. Multiple types of desired materials may be printed with alignment over the pre-defined template. The patterned openings mechanically constrain the deposition of material onto specific areas on the surface. After printing, the polymer template can be peeled off to reveal uniformly patterned array features, despite the imperfect morphologies of the original printed spots. This technology has applications in micro- and nano-arrays for molecular biology, biochemical sensors, and semiconductor manufacturing.

Improved Ultra-Fast Fiber Laser

  1. Frank Wise
    Applied & Engineering Physics, Cornell University
    Andy Chinyu Chong
    Applied & Engineering Physics, Cornell University

    Femtosecond lasers are ultra-fast lasers useful in manufacturing, research and medicine. Fiber lasers also offer many advantages, including lower cost, smaller size and increased robustness over non-fiber lasers. An all-fiber femtosecond laser, therefore, will provide all such advantages for useful applications. Group-velocity dispersion (GVD), however, causes laser pulses to spread in optical fibers and hence will degrade the signal power over distance. In the past, anomalous approaches using prisms, diffraction gratings, and chirped mirrors have been implemented in partial-fiber and non-fiber lasers to compensate for GVD, which generally plagues femtosecond lasers at the cost of significantly reducing the power of the laser pulses. An all-normal dispersion (ANDi) laser has been developed at Cornell. Combined with other fiber laser technologies developed or co-developed at Cornell, such as the carbon nanotube fiber saturable absorber, the first practical true all-fiber femtosecond laser can now finally be built.

Novel Fabrication Method for Ultrathin Layers of Graphene with High Electrical Properties

  1. Jiwoong Park
    Chemistry & Chemical Biology, Cornell University
    Carlos Ruiz-Vargas
    Applied & Engineering Physics, Cornell University
    Mark Levendorf
    Chemistry & Chemical Biology, Cornell University

    This invention describes unique growth and fabrication methods for graphene. Graphene is a single layer of carbon atoms, hexagonally-bound, with potential to become the optimal material for the new generation of transistors. The most significant advantage of this unique technology versus older methods is that it eliminates the troublesome separation and transfer step of graphene from the substrate to the target. The transfer step carries the risk of damaging the delicate single layer graphenes (SLG) and reducing the integrity, thus diminishing the conductivity of the layer. By the novel method, the graphene is grown directly on an evaporated copper thin film. Notable improvements over existing techniques include higher carrier mobility and mechanical and electrical continuity over a large distance.

Structurally Precise Materials for Organic Solar Cells

  1. William Dichtel
    Chemistry & Chemical Biology, Cornell University
    Eric Spitler
    Chemistry & Chemical Biology, Cornell University

    Organic solar cells have attracted significant basic research interest and commercial investment in recent years. These devices are inexpensive, easy to manufacture, lightweight, and can be mechanically flexible. However, the organic materials are much less efficient than their inorganic counterparts because they lack the long-range order required to transport charge over long distances. This invention describes a new method for preparing robust, ordered, and highly absorbent organic materials designed for improved photovoltaic performance.

Universal Gripping "Hand" for Robots

    Mechanical Engineering, Cornell University
    Hod Lipson
    Mechanical & Aerospace Engineering, Cornell University

    Robotic grippers for objects of unfamiliar shape and surface properties typically require complex sensory feedback. This alternative approach is based on jammable media. The highly adaptive system uses no active gripping controls and excels at fast grasping of single or multiple objects, complicated shapes, variable sizes and different weights. It allows robots to pick up objects from paper clips to bricks without active feedback from the hand.

    Physics, Cornell University

    A high quality factor micro- or nano-mechanical (M/NEMS) resonator acting as a pressure sensor is presented. A semi-encapsulated volume of gas exhibits stiffness changes when it is squeezed. Taking advantage of this effect, the inventors designed a drum-type resonator with a resonance frequency that is linearly proportional to pressure. These low cost pressure sensors can be used in automotive, aerospace, and industrial fields. Other M/NEMS structures have also been designed for a variety of biochemical and real-time atmospheric gas sensor applications.

    This invention enables hitless operation of a broadband compact electro-switch for on-chip optical networks on a silicon platform. A broadband switch is important for two main reasons: low distortion of high bandwidth signals and robustness from on-chip temperature changes. This is the first demonstration of a broadband, hitless, compact electro-optic switch on a silicon photonics platform, using a compact broadband filter integrated with PIN diodes. This technology has applications in telecommunications, optical switching, and multiplexed optical signals.
