FIGURE 7.

Bacterial attachment on glass, Fn monolayer, PLL₃₀ monolayer, and (PLL₃₀-Fn)₁₀ thin films after 2 h of incubation. (A) Percentage of adherent S. aureus, S. epidermidis, and S. mutans on Fn monolayer, PLL₃₀ monolayer, and (PLL₃₀-Fn)₁₀ films normalized to bacteria adhered on glass (n = 7). No S. aureus are found to adhere to (PLL₃₀-Fn)₁₀ thin films. Data are normalized for each strain to their respective glass control mean. Error bars indicate the standard deviation on the mean normalized data. (B) Representative images of LIVE/DEAD staining of adherent S. aureus on glass, Fn monolayer, PLL₃₀ monolayer, and (PLL₃₀-Fn)₁₀ thin films (n = 3). The magnified captions correspond to the area surrounded by dashed rectangles in the original images. Note: Green indicates live bacteria, red indicates dead bacteria. Scale bar = 10 μm. Statistically different at p < 0.05.
