a Schematic illustration of the construction of CuS–BSA–FA as a vehicle to deliver ICG showing the mechanism of PDT and PTT therapies. b Cytotoxicity assays on HeLa cells in the presence of CuS–BSA–FA, ICG and CuS–BSA–FA/ICG with or without NIR irradiation (1 W cm−2 for 5 min). c HeLa cells in the presence of CuS–BSA–FA (60 mg mL−1), ICG (2 mg mL−1) and CuS–BSA–FA/ICG (60 mg mL−1 for CuS–BSA–FA and 2 mg mL−1 for ICG) with and without laser irradiation (1 W cm−2).
