What About Bacteria?

This recent 2020 study makes it quite clear that most bacteria don't stand a chance against AgNP's.

"Cultures were prepared with agarose and inoculated with the following bacterial strains: Bacillus cereus (Gram +), Micrococcus luteus (Gram +), Staphylococcus aureus (Gram +), Escherichia coli (Gram -), Citrobacter freundii (Gram -), Enterobacter aerogenes (Gram -), Klebsiella pneumoniae (Gram -), Proteus mirabilis (Gram -), Proteus vulgaris (Gram -) and Serratia marcescens (Gram -). Preliminary tests showed an inhibition diameter that surpassed 1.0 cm in all bacterial strains. We expect our Ag NPs to have a potential antibacterial activity towards all types of bacteria, due to oxidation of silver (Ag ⁰ to Ag ⁺ )."
