Photothermal performance of LIPC upon laser irradiation. A UV–vis absorbance spectra of LIPC, LDH and free ICG. B Temperature change profiles and C photothermal images of LIPC under laser irradiation (808 nm, 0.5 W/cm2) for 5 min. The concentrations of ICG were 0–20 µg/mL and the mass ratio of LDH to CCM was 20:1
