a UV-Vis-NIR absorbance spectra of AgPd PB nanozyme of varying concentrations. b Temperature change curves of AgPd PB nanozyme aqueous solutions with different concentrations upon 1064 nm laser irradiation. c A single heating and cooling cycle of AgPd PB nanozyme under 1064 nm laser irradiation (1.2 W·cm^-2) and d linear time data versus − lnθ obtained from the cooling period. e Photothermal conversion cycling test of AgPd PB nanozyme under 1064 nm laser irradiation (1.2 W·cm^-2). f Measured temperature change of AgPd PB nanozyme solution (200 µg·mL^-1) versus the depth of covered chicken breast tissue under 808/1064 nm laser irradiation; an exponential decay function was used to fit the experimental data, while a schematic illustration of the measuring setup was shown in the inset
