摘要: The real-time tracking and adjustment of the disassembly status hydrogels in vivo are important challenges to accurate precise assessment. In this article, a photothermally controllable, visible, dual fluorescent thermosensitive hydrogel was designed developed based on porphyrin-poly(ethylene glycol)/IR-820-α-cyclodextrin hydrogel. Due photothermal effect fluorescence emission IR-820, it can exert functions control imaging tracking. IR-820 conjugated regulate by IR-820. Furthermore, each component be tracked porphyrin. Fluorescence remote were merged into visible controlled after subcutaneous injection using mice as models. visualization cyclodextrin/poly(ethylene glycol) revealed process component, efficiently accelerated under laser irradiation with This affords an basis for understanding poly(ethylene glycol)/α-cyclodextrin
