Fig. 8. (A) Morphological images of U87MG cell after incubation with different samples (CuS NPs, CuS@BSA, CuS@BSA-MBA and CuS@BSA-MBA-cRGD) and * irradiation by NIR laser (808 nm, 1.0 W cm⁻²) for 5 min; (B) quantitative analysis of CuS NPs, CuS@BSA, CuS@BSA-MBA and CuS@BSA-MBA-cRGD on the growth inhibition of U87MG cells at different concentrations (10, 40, 80, 120, 160, 200 μg mL⁻¹) after irradiated by NIR laser for 5 min, the NIR group was irradiated by 808 nm only and served as a control group.
