Fig. 10

S. aureus or E. coli were incubated for 24 h on control or NW-850-5 surfaces under the same growth conditions used for proteomic analysis. Following 24-h incubation, the levels of H2O2 were determined by ROS-Glo a. Values given are mean ± standard deviation and individual data points for each mean are shown. ** indicates P ≤ 0.01 relative to control for S. aureus (P = 0.003) and E. coli (P = 0.01), as determined by a two-sided Student’s t-test; n = 3 performed in duplicate. Representative SEM micrographs of S. aureus b, c and E. coli d, e incubated on control or NW-850-5 are shown. Insets show higher magnification SEM images of each surface.
