Antibacterial Effects Of Silver Naked Nanoparticles

Andrew Walayat, Andrews University


The antibacterial effects of variants of silver naked nanoparticles on E. coli and S. epidermidis were assessed through colony counts and estimated plate coverage. The antibacterial effects of rhodanine-functionalized nanoparticles were also attempted through this process. The relative antibacterial power was examined through administration of antibiotic sensitivity discs of varying synthesis practices to Petri dishes containing bacteria, measuring diameter of zones of inhibition in mm. All fractions exhibited significantly less growth than control fractions, but none were significantly more effective. The rhodanine-functionalized naked nanoparticles showed significantly less growth than rhodanine or silver oxide controls. Results were apparent in both bacteria.
