A Hemolysis ratio of red blood cells incubated with Au@Cu2-xSe NPs at various concentrations for 5 h. B Routing blood analysis and C hepatic and kidney function analysis of control and experiment groups for in vivo toxicity evaluation after intravenous injection of saline or Au@Cu2-xSe NPs. Data are presented as mean ± s.d. (n = 3). D H&E staining on major organ tissues of control and experiment groups for in vivo toxicity evaluation after intravenous injection of saline or Au@Cu2-xSe NPs. Scale bar = 50 μm. Saline: 200 µL. Au@Cu2-xSe: 2 mg mL−1 in saline, 200 µL
