In vitro cell experiments. (a) Relative viability of cells incubated with gradient CuS–Fn NCs concentrations with or without irradiation by 808 nm laser. (b) Relative viability of U87MG cells incubated with 10 µg/mL CuS–Fn NCs after irradiation by 808 nm laser. (c) Fluorescence images of calcein AM/PI stained U87 MG cells after 4 h incubation with fresh medium, CuS–Fn NCs, and CuS–Fn NCs exposed to 808 nm laser. A clear laser spot can be seen in the irradiated CuS–Fn NCs group. Scale bar 100 µm.
