Fig. 4: Antibacterial activities of IS/MB.

a Quantitative analysis of bacterial colonies for various materials against MRSA after 15 min visible light (λ ≥ 420 nm, 110 mW cm−2) irradiation. No catalyst was added to the bacterial solution of the control group. Data are presented as mean ± s.d. (n = 4). The measurements of bacterial colonies were taken from distinct samples. Data are shown as box-and-whisker plots, with the median represented by the central line inside each box, the 25th and 75th percentiles represented by the edges of the box, and the whiskers extending to the most extreme data points. b Activity comparison of IS/MB-20 with reported state-of-art photocatalysts against MRSA. The inset image in Fig. 1b is the ruler of the bubble. c CLSM overlay projections of live (green fluorescent) and dead (red fluorescent) bacteria. The percentages of green and red fluorescent are plotted in the images. Scale bar: 50 µm. d Coagulase assay of MRSA treated with IS/MB-20 at different times. e Clustering heatmap for expression changes of DGEs. Red represents high expression of genes in the sample, and blue represents low expression. f Size of the MRSA-infected wound of mice during treatment with different materials for 10 days. Data are presented as mean ± standard deviations from a representative experiment (n = 3 independent samples). P-values were analyzed by a one-way ANOVA test.
