Metasurfaces make quantum dot films cooler where they emit more efficiently, turning light-controlled temperature gradients into self-powered electrical signals.
A spiky nanoparticle activated by ultrasound clears drug-resistant bacterial biofilms, mechanically piercing them while releasing two reactive oxygen species, each tuned to reach a different depth.
Nanozyme-modified polyethylene liners reduced wear debris and made remaining particles less inflammatory, lowering oxidative stress and bone loss in implant models.
