Figure 7.
Comparison of the number of bacteria adhered on the unit area of surfaces (1 mm2×1 mm2) during the 2 h incubation in PA solution and briefly washed by PBS buffer. Values are averages with standard deviations of 10 pictures conducted on a minimum of three separate experiments. * denotes significant difference in terms of the antibacterial rate compared to the unmodified control (p<0.01, T test).
