Figure 8. — Cytotoxicity in vitro. Viability of L929 cells co-cultured with different solutions (0.2 mM) (a, c) and at different concentrations of CuS-PNIPAm NPs (0.1–0.5 mM) (b, d) without (a, b) and with NIR irradiation (c, d). NIR irradiation proceeded for 1 min by a laser with 808 nm, 2 W/cm². (e) Photographs and hemolysis ratio of RBCs for H₂O (positive control), PBS (negative control), CuS NPs, CuS-PEG NPs and CuS-PNIPAm NPs (n = 3). (f) Morphology of RBCs after hemolysis assay.
