a Illustration showing the near-infrared photothermal and photodynamic therapeutic effect of plasmonic Cu2–xS NCs. b The intensity of ESR for the spin trapped hydroxyl radical produced by Cu2–xS NCs at various concentrations and light power densities. Viability of B16 cells at different concentrations of Cu2–xS NCs with and without NIR irradiation (808 nm, 2.3 W cm–2 for 3 min) measured after 24 and 48 h incubation. c Corresponding IC50 value of each group for 24 and 48 h. d Comparative efficacy study of single intratumoral injection in B16 xenograft bearing nude mouse models showing the mean tumor volumes for the Cu2–xS-NIR group.
