Nanoparticles as Catalyst for Formation of Rigid Organic Polymers with Controlled Polymerization

Overview Polybenzoxazole (PBO) fibers have usually been made by condensing diaminobenzene diol and terephthalic acid with polyphosphoric acid (PA), which serves as both solvent and catalyst. The use of PA, however, causes the PBO fibers to be contaminated with PA units. We have invented a nanoparticle (NP)-based catalytic method to synthesize functional...

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...
