Novel Chromogenic Beta-Lactamase Substrate for Diagnostic Biomaterials
Overview Chromogenic beta-lactamase substrates are used to diagnose bacterial infections. Yet those currently available lose their diagnostic color-change capability when chemically modified. We have synthesized a novel chromogenic beta-lactam molecule (“ANT”) that retains its color-change response when modified for conjugation to a range...

𝜷‐Lactamase-Responsive Degradable Hydrogels
Overview Antibiotic-resistance poses a serious public health problem. We have developed a hydrogel (hydrated polymer network) that is sensitive to β-lactamases, a class of enzymes released by a variety of harmful bacteria. In the presence of β-lactamases, the hydrogel degrades, releasing the therapeutic agent it contains. Market Opportunity The...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
