The rheological properties and in vitro photothermal properties of hydrogel platform. A The thermoresponsive behavior of gel and Mgel. B The sol–gel phase transition time of gel and Mgel. C IR thermographic images of Mgel with different concentrations of IR820 after exposure to an 808 nm laser at a power density of 1 W/cm2. D The temperature–time profile of IR820/Mgel with different concentrations of IR820
