In vitro targeted PTT of S. aureus biofilms. (A) Temperature changing curves of S. aureus biofilms under 785 nm laser irradiation (0.58 W/cm2, 10 min) after 6 h incubation with saline, MPP NSs, and MPPI NSs (MoS2: 160 μg/mL), respectively. (B) Bacterial viability and (C) Three dimensional (3D) confocal laser scanning microscopy (CLSM) images (630 × 630 μm) of S. aureus biofilms with or without NIR laser irradiation after incubation with different concentrations of MPP NSs or MPPI NSs. (D) Representative SEM images of S. aureus biofilms after PTT of MPP NSs or MPPI NSs (MoS2: 160 μg/mL). The scale bars in upper row and lower row represent 2 μm and 500 nm, respectively.
