Figure 1

Bactericidal tests using different diluent solutions. The reaction solution obtained after UV-A irradiation was diluted with ultrapure water (UW), 10% NaCl, 10% albumin solution, or MHB solution. Significant differences (p < 0.05) between the groups are denoted by different superscript letters (i.e., bars with the same letter are not significantly different). Ag(+)L(+): Mixture of silver nitrate solution (40 μM)and bacterial suspension (107 CFU/mL) with UV-A irradiation for 1 min, Ag(−)L(−):Mixture of ultrapure water and bacterial suspension (107 CFU/mL) without UV-A irradiation.
