Functional Manipulation of the Gut Microbiome Using a Personalized Approach

The use of traditional probiotic microorganisms to provide therapeutic function for the gut microbiome has a number of limitations. Probiotic bacteria do not colonize the gut because they can’t compete with the resident flora that have evolved for that environment. Current probiotics are a single strain which when used in multiple hosts have not had great success in broad populations and are therefore unpredictable. To alleviate the above problem, a new approach is necessary to colonize the human gastrointestinal tract with greater reliability and for therapeutic value to the patient. 

An Osteoadsorptive Fluorogenic Substrate of Cathepsin K for Imaging Osteoclast Activity and Migration

UCLA researchers in the Department of Dentistry have developed a novel fluorescent probe for studying the role of osteoclasts in bone diseases and for detecting the early onset of bone resorption by targeting an important protein Cathepsin K. This probe can also deliver drug molecules to bone resorption sites with high specificity.

A cast molded methodology for creating polymeric heart valves and vessels with calcium apatite inclusions. The heart valves and vessels can then be implanted in animals to test cardiovascular medical device efficacy.

Bioorthogonally-Engineered Extracellular Vesicles for Applications in Detection and Therapeutic Delivery

Extracellular vesicles (EVs) are promising as drug delivery carriers because they are inherently biocompatible, It would be desirable to efficiently, specifically, and rapidly change the EVs surface presentation to program the interactions with its target cells. Inventors at UC Irvine have developed a strategy for functionalizing the cellular membranes of EVs with precision and ease.

Antimicrobial, Stimuli-responsive Polysaccharide

State of the art antimicrobial therapeutics, while effective and promising, remain only short-term solutions to the overall challenge of drug-resistant microbes. UCI researchers have developed a chitosan-based nanoantibiotic that is non-toxic and carries potential for broad spectrum use.

Pressure Based Mechanical Feedback to Safely Insert Catheters

A pressure sensing device that provides feedback during the insertion of a ureteral access sheath to prevent unwanted damage to the wall of the ureter.

Controlled-Release Cysteamine Nanowafer For Treating Corneal Cystinosis

Corneal cystinosis is a rare metabolic disease that causes loss of vision. Researchers at UCI have developed a nanowafer drug delivery system that has demonstrated twice the therapeutic efficacy during in vivo studies in mice.

Self-Calibrating Hollow Microneedles

A new approach for building self-calibrating hollow microneedles that can be transferred to an electronic die or other substrates.

Active Nanoplatform with High Drug Loading Capacity for the Diagnosis and Treatment of Cancer

Researchers at the University of California, Davis have developed an active nanoplatform (F/HAPIN) for cancer diagnosis and therapy.

Sealed Nanostraw Microdevices For Oral Drug Delivery

This invention is a nanostraw device that is built upon microdevice technology for oral drug delivery. It is the first example of a microdevice for oral drug delivery, with the drug sealed in by a semi-permeable membrane for (1) in-solution drug loading, and tunable drug release, (2) increased bioadhesion for prolonged drug exposure, and (3) protection of drug from outside biomolecules.

Nanowire-Coated Planar Microdevices For Transmucosal Drug Delivery

This invention describes a first-of-a-kind methodology using micro- and nanofabrication techniques to create polymeric microscale devices that are asymmetrically coated with nanowires. The nanowire coating provides an inherent high-throughput, low-waste drug loading mechanism, enhanced cytoadhesion, and may potentially interact with epithelial tissue to enhance drug permeation.

Single Ended Draw Lines For Medical Device Application

Minimizing the movement of deployed transcatheter heart valves and stents during detachment using single ended draw lines.

Novel Nanoliposomal Nitroglycerin Formulation for Cardiovascular Therapies

    To address this major limitation, investigators at UCR have developed a nanoliposomal formulation of NTG, which achieves a 70-fold increase in the anti-inflammatory effect of NTG when compared to NTG. This increase in potency allows lower doses to be effective, which could mitigate the common issues seen with high clinical doses of NTG viz. loss of NTG sensitivity and endothelial toxicity. Fig. 1 Adhesion of U937 monocytes to NO-deficient (L-NIO-treated) ECs is significantly blocked by treating ECs with 5 ug/ml nanoliposomal nitroglycerin (NTG-NL). L-NIO is a selective eNOS inhibitor.  Remarkably, this anti-inflammatory dose of NTG in nanoliposomes is 70-fold lower than the dose of free NTG (5uM) required to achieve a similar effect
