Figure 2. PTNP are taken up by bacterial biofilms.

Figure 2

SEM in backscattered electron (BSE) mode showing the morphology of (A) untreated biofilm, (B) PTNP-treated S. mutans biofilm (Scale bar: 10 μm). Red arrows show nanoparticles. (C) ICP-OES measurements on S. mutans biofilms. TEM of S. aureus biofilm uptake of PTNP, (D) untreated biofilm, and (E) S. aureus biofilm treated with PTNP for 24 hours (Scale bar: 1 μm). (F) ICP-OES measurements on S. aureus biofilms, (n = 6). Red arrows show nanoparticles. Statistical analyses used a mixed-model ANCOVA with SAS 9.5 software from SAS Institute. *P < 0.05, **P < 0.005. The data are presented as mean ± SD.
