In vivo antibacterial performance of Cu SASs/NPC. (a) In vivo antibacterial protocol in mice. (b) Temperature change curves of mice treated with Cu SASs/NPC after 808 nm laser irradiation (1.0 W/cm2, 2 min). (c) Wound area, and (e) wound photographs of mice after various treatments at different treatment time. (d) Quantitative analysis and (f) photographs of bacterial colonies after 5 days treatment. (g) H&E and (h) Masson staining of the bacteria infected tissues after different treatments. Statistical analysis was performed using the Student's two-tailed t-test (***P < 0.001, **P < 0.01, and *P < 0.05).
