Abstract

A bio-responsive microneedle-based patch, integrated with a rhodamine-stained glucose-signal amplifier and calcein-AM-stained pancreatic β-cell capsules, is developed by Z. Gu and co-workers. This "smart cell patch", described on page 3115, effectively regulates the blood glucose level of type-1 diabetic mice, achieving a reduction for over 10 h. Image credit: Yanqi Ye.
