Abstract
- Glucose-sensitive membrane has potential application in self-regulating insulin release. Phenylboronic acid (PBA) is a well-known glucose reporter. Unfortunately, most PBA-based glucose-sensitive materials are expansion-type, which are not suitable as chemical valves in membrane pores for self-regulating insulin release. According to a new glucose-sensitive mechanism, we synthesized PBA-based contraction-type glucose-sensitive liner polymer and microgels. Herein, a glucose-sensitive membrane was prepared by grafting PBA-based contraction-type glucose-sensitive linear polymer on the membrane surface. Through adjusting the chain length and chain density, the glucose-sensitivity of the membrane was optimized. The membrane can reversibly regulate insulin release at physiologically relevant glucose concentrations in simulates body fluids and fetal bovine serum. The membrane also has good stability, anti-fouling and biocompatibility. It has potential application in self-regulating insulin release. [ABSTRACT FROM AUTHOR]
