MICRONEEDLE-ARRAY PATCHES WITH GLUCOSE-RESPONSIVE MATRIX FOR CLOSED-LOOP INSULIN DELIVERY

摘要

Disclosed are compositions and methods for microneedle patches comprising copolymer designed for glucose triggered insulin delivery. In one aspect, disclosed herein are microneedle patches comprising insulin loaded copolymers; wherein the insulin dissociates from the microneedle in an hyperglycemic environment; wherein the copolymer comprises poly(N-vinylpyrrolidone-co-2-(dimethylamino)ethyl acrylate-co-3-(acrylamido)phenylboronic acid and methods of their use.
