(a,b) Quantitative temperature curve of TCPR NPs with different concentrations at pH 7.4 and 5.5 (1060 nm, 1 W cm−2, 10 min). (c) Temperature variations of TCPR NPs (100 µg mL−1) irradiated by 1060 nm laser at different power densities. (d) Photothermal stability of TCPR NPs exposed to laser irradiation (1060 nm, 1 W cm−2) for 5 on/off cycles. (e) Photoacoustic (PA) images of TCPR NP suspensions at various concentrations (25–100 µg mL−1). (f) Quantitative PA intensities corresponding to the PA signals in (e).
