▎ 摘　　要

NOVELTY - Photothermal self-driven material is a composite material with a microstructure on surface. USE - Photothermal self-driven material for delivering exogenous substances into cells by wearable device for subcutaneous hair follicle repair, angiogenesis, wound healing, nerve therapy, tumor healing and diabetes treatment (all claimed). ADVANTAGE - The material quickly loads various exogenous substances, shortens the transmission path of exogenous substances, undergoes photothermal conversion after light irradiation, and the generated heat can reversibly rupture the cell membrane, further improves the intracellular delivery efficiency and cell activity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing the photothermal self-driven material, which involves: (a) mixing photothermal nanoparticles into the elastomer to prepare a photothermal nanoparticle/elastomer mixture; (b) putting the photothermal nanoparticle/elastomer mixture into a container, and curing to obtain a photothermal self-driven material with a microstructure on the surface; (2) a wearable device, which has the photothermal self-driving material and an exogenous substance, where the exogenous substance is loaded on the photothermal self-driving material; (3) a method for preparing a wearable device, which involves: (a) inserting exogenous substances into photothermal self-driven materials with microstructure on the surface to obtain wearable devices that store exogenous substances; (4) a method for delivering exogenous substances into cells by a wearable device, which involves: (a) applying a wearable device loaded with exogenous substances to the epidermis, and illuminating the wearable device.
