Silver Nanoparticles: Biosynthesis Using an ATCC Reference Strain of Pseudomonas aeruginosa and Activity as Broad Spectrum Clinical Antibacterial Agents

Figure 2

UV-visible spectra of Ag-NPs biosynthesized (black line), AgNO₃ solution (gray line), and P. aeruginosa culture supernatant (control, dotted line). The absorption of Ag-NPs was recorded after the addition of a culture supernatant of P. aeruginosa at 30% by volume to 10 mM AgNO₃ solution. The curve was recorded after 24 h of incubation.
