A Fentanyl‐Responsive Microneedle Patch for Harm Reduction

Advanced Science, EarlyView.
A fentanyl‐responsive microneedle patch is developed as a self‐regulating overdose intervention that releases naloxone upon detecting fentanyl. The system employs aptamer‐functionalized nanoparticles embedded in a swellable polymer matrix to enable rapid, on‐demand drug delivery through the skin.

Outstanding TC Enhancement in 5d–3d Y2NiIrO6 by Compression

Advanced Science, EarlyView.
Double perovskite Y2NiIrO6 with half filed 3d eg–5d t2g configuration, exhibits first experimental example of pressure‐enhanced magnetic interaction in iridate and iridate‐related systems. Its Curie temperature increase from 192 to 243 K at 17 GPa. Herein, the orthogonal eg–t2g pathway remains robust even under compression‐induced lattice distortion ...
