Fig. 3. Photothermal performance of Au-stomatocytes and control particles upon laser irradiation.

a Temperature changes of Au-stomatocytes at different particle concentrations (0 mg mL⁻¹, 1 mg mL⁻¹, 2 mg mL⁻¹, and 3.33 mg mL⁻¹) upon laser irradiation (660 nm, 1.5 W, 10 min), data represent mean ± SD for n = 3 independent samples. Error bar represents the standard deviation (n = 3). b Temperature change profiles of irradiated aqueous media (660 nm laser irradiation, 1.5 W, 10 min) containing pure water, stomatocytes, Au-stomatocytes, and Au-polymersomes (all at concentrations of 3.33 mg mL⁻¹), data represent mean ± SD for n = 3 independent samples. Error bar represents the standard deviation (n = 3). c Temperature change of an aqueous sample containing Au-stomatocytes (3.33 mg mL⁻¹) as a function of input laser power (660 nm), data represent mean ± SD for n = 3 independent samples. Error bars represent the standard deviation (n = 3). d Photothermal stability of an aqueous sample containing Au-stomatocytes (3.33 mg mL⁻¹) upon cyclic laser irradiation (660 nm, 1.5 W). e Infrared thermographic maps of aqueous samples containing Au-stomatocytes, pure stomatocytes, pure water, and Au-polymersomes at a concentration of 3.33 mg mL⁻¹ as a function of irradiation time under 660 nm irradiation (1.5 W).
