A, B Haemolytic profile of red blood cells after incubation with various concentrations of MB@OVA/PPY NPs for 2 h (1, PBS; 2, water; 3–5, 50–400 µg/mL NPs). C Cytocompatibility of the MB@OVA/PPY NPs. The effects of PTT mediated by MB@OVA/PPY NPs on MEF (D) and 4T1 cell (E) viability under 808 nm NIR irradiation at a power intensity of 1.0 W/cm2 for 5 min. F The effect of combined photothermal and photodynamic treatment mediated by MB@OVA/PPY NPs on 4T1 cell viability in vitro (1. Control; 2. 808 nm laser; 3. 660 nm laser; 4. 808 nm + 660 nm laser). p values were calculated by Student’s t test. Values are reported as the means ± SD (n = 3) of three independent experiments, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.001
