Figure 2.
Logarithmic reduction of bacterial load after incubation on provided coatings.
Notes: Bacterial suspensions (400 µL, of approximately 105 CFU/mL) were cultured on substrates (stainless steel or glass, as indicated by hatches in top of graphs) coated with antimicrobial agents. Logarithmic reduction in bacterial load after 24 hour incubation, compared with the control substrate (stainless steel or glass alone) is depicted. Bars represent values of pooled triplicate samples obtained from (A) nanomaterial-based coatings and (B) coatings based on other antimicrobial agents.
Abbreviation: AMC, antimicrobial coating.
