Figure 6

Antibacterial rates observed after substrates were immersed PBS for 1–28 days against E. coli (A) and S. aureus (B). Fluorescence images of adhered E. coli (C) and S. aureus (D) after substrates were soaked in PBS for 28 days. Died and alive bacteria are red and green in color, respectively. All values are averages calculated from four independent measurements. Errors are standard deviations ***p < 0.001 compared to metallic Ti substrate.
