Abstract: To overcome the pain and risk of hypoglycemia in insulin administration, glucose-responsive microneedles have been developed by researchers, which could release insulin according to the blood glucose level. We designed a kind of particles by a RAFT method containing a phenylboronic acid group as the sensor of glucose and carrier of insulin. Polyethylene glycol (PEG)-DDMAT was synthesized as a macromolecular RAFT agent, which was then reacted with 3-acrylamidophenylboronic acid (AAPBA) to synthesize the block copolymer PEG-b-PAAPBA. Glucose-responsive particles loaded with insulin were prepared by self-assembly based on hydrophilic-hydrophobic interactions. Microneedle patches loaded with glucose-responsive particles were prepared using hyaluronic acid as the substrate. The insulin release behavior of the particles in glucose solutions of 0, 100, and 400 mg/dL showed significant glucose responsiveness and good biosafety. The results of blood glucose control experiments in rats indicate that a single microneedle patch can effectively maintain normal blood glucose for over 7 hours.
