Abstract
AbstractIntelligent hydrogels are materials with abilities to change their chemical nature or physical structure in response to external stimuli showing promising potential in multitudinous applications. Especially, photo‐thermo coupled responsive hydrogels that are prepared by encapsulating photothermal agents into thermo‐responsive hydrogel matrix exhibit more attractive advantages in biomedical applications owing to their spatiotemporal control and precise therapy. This work summarizes the latest progress of the photo‐thermo coupled responsive hydrogel in biomedical applications. Three major elements of the photo‐thermo coupled responsive hydrogel, i.e., thermo‐responsive hydrogel matrix, photothermal agents, and construction methods are introduced. Furthermore, the recent developments of these hydrogels for biomedical applications are described with some selected examples. Finally, the challenges and future perspectives for photo‐thermo coupled responsive hydrogels are outlined.
