Hydroxyl Radical Generating Monovalent Copper Particles for Antimicrobial Application
Figure 3
Antimicrobial activities of CuO (150°C) and CuxP (200–350°C) particles on model bacteria. (a–e) exposure of Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria to 8–256 mg/L particles at 37°C, 16 hr. The extent of biomass growth was determined relative to cell-only (no particles) control samples. For each of the particle concentration, the experiments were performed with three biological replicates (independent bacterial inocula), each with three technical replicates. (f) The minimum inhibitory concentrations (correspond to ≤5% growth relative to the cell-only control samples) for each of the particle exposure systems.
