Antibacterial Properties of Silver-Loaded Plasma Polymer Coatings

Figure 4

Number of E. coli adhered after 2 h of growth on HA film (“HA”), loaded with SNPs (“HA + SNPs”), and recovered by a second HA layer of 6 nm (“6 nm”), 12 nm (“12 nm”), and 18 nm (“18 nm”) of thickness. Results were obtained by analysing CLSM micrographs with ImageJ software. § and # symbols indicate significant difference compared to HA (𝑃<0.005 and 𝑃<0.05 resp.).
