Quasi-photonic crystals-boosted highly efficient TiCT MXene photothermal materials for untethered actuators and therapeutics.

The near-perfect internal photothermal conversion efficiency of MXene has made them ideal candidates for diverse applications. However, the photothermal performance of MXene was limited by the low optical absorption, resulting in low overall conversion efficiency and inferior heating efficacy. Herein, we proposed a facile and universal method for obtaining high-efficiency photothermal systems simply by vacuum-filtrating polytetrafluoroethylene nanoparticles (PTFE NPs) on typical photothermal materials, e.

Microneedle Arrays for Near-Infrared-Controlled Insulin Delivery Based on Thermosensitive Microgel.

Insulin delivery plays a crucial role in diabetic treatment. Regular painless administration methods are not ideal for insulin delivery due to their insufficient bioavailability and inefficiency. In this study, dissolving microneedle array patches containing a thermosensitive insulin carrier P(NIPAm-AAm) microgel (MG) and the photothermal agent MXene were prepared with drug-protected protocols for near-infrared (NIR) light-controlled painless and minimally invasive insulin delivery.
