In vivo photothermal conversion and anti-MRSA performances. (A) Near-infrared photothermal images of mice. (B) The local temperature curves of the infected skin (n = 5). (C) Representative images showing the subcutaneous abscess in MRSA-infected skin after different treatments. (D) Photographic images of in vivo MRSA colonies cultured on agar plates. (E) The number of in vivo viable MRSA that expressed as lg (CFU/mL) (n = 5). Note: ns signified no significant difference vs control, ∗∗p < 0.01 vs control, ∗∗∗p < 0.001 vs control, ^#p < 0.05 vs PZH MNs + NIR. (F) The bacterial survival rate relative to the control (n = 5).
