Description
Xu and co-authors present a 2026 study on 3D-printed microneedle arrays coated with silver for skin treatments. Polymer needles promise painless delivery, but tall thin ones tend to shrink, bend, or carry heat poorly. The team brewed a low-shrinkage resin made for precision printing. Printed arrays then gained an even silver skin through a room-temperature chemical bath.
The coating lifted heat conduction thirty-seven-fold over bare polymer. Strength tests passed, and needles pierced lab skin models and pig skin with low force, leaving stable channels. Cell safety held both before and after coating. The authors target energy-assisted skin therapies that need needles both sturdy and heat-ready.
