Integrated O2 and H2 Gas Therapy via Microneedle‐Assisted Photocatalytic Water Splitting for Accelerating Diabetic Full‐Thickness Skin Wound Healing

Advanced Science, EarlyView.
A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via

Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management

Advanced Science, EarlyView.
A programmable self‐heating microneedle patch enables on‐demand, timed‐sequence insulin delivery via user‐triggered quadrant activation. Each activation generates localized heat that melts a phase‐change barrier, accelerating drug release. In diabetic rats, sequential quadrant activation counteracts four meal‐mimicking glucose spikes over 24 h without ...
