Fig. 1From: A combination of silver nanoparticles and visible blue light enhances the antibacterial efficacy of ineffective antibiotics against methicillin-resistant Staphylococcus aureus (MRSA)Antimicrobial activity of the AgNPs at different concentrations in combination with blue light against MRSA isolates. Cell suspensions were exposed to either the silver compound alone at sub-MICs (a 1/2, b 1/4, c 1/8, and d 1/16 MIC), or blue light alone at 460 nm and 250 mW for 1 h, or combination of both agents. Viable colony count was recorded as mean ± SD of three independent experiments.
