Fig. 7. Antibacterial efficacy of NO releasing polymer surfaces in planktonic assays against MRSA under nutrient poor conditions (PBS) after 4 (A) and 24 hours (B) incubation. Graph C shows the results obtained with NO releasing polymer surfaces in a 24-hour biofilm assay with MRSA under nutrient poor conditions. Values represent mean ± SD (n = 3; ***P ≤ 0.001; ** P ≤ 0.01; *P ≤ 0.05). Red represent SD from polymer control coated samples, black from bacterial control only.
