Figure Lengend Snippet: Antimicrobial activity of multi-mode periosteum scaffolds with different NIR irradiation strategies. A. Representative images of MRSA and E. coli colonies with different treatments. Quantitative analysis of MRSA ( B ) and E. coli ( C ) colonies in (A), respectively (n = 3). Results are presented as means ± SD. Samples were subjected to one-way ANOVA with Tukey's post hoc test. Ns ( p > 0.05), ∗∗ p < 0.01. D. Representative SEM images of MRSA and E. coli colonies with different treatments. Scale bar: 1 μm. E. Live/dead staining of MRSA and E. coli colonies in different treatment groups. Scale bar: 100 μm. F. Confocal microscopy image of MRSA biofilm. Scale bar: 100 μm. Protein leakage statistics for MRSA ( G ) and E. coli ( H ), respectively (n = 3). Results are presented as means ± SD. Samples were subjected to one-way ANOVA with Tukey's post hoc test. ∗∗ Significant differences of group M + CI vs. NC, M, and M + II, p < 0.01.
