Evidence for differentiated ionic and surface contact effects driving bacterial inactivation by way of genetically modified bacteria

Abstract

New evidence is presented for the bacterial inactivation of E. coli presenting normal porins on sputtered Ag–Cu surfaces compared with similar E. coli porinless bacteria. Inactivation at a reduced rate was observed on the genetically modified porinless bacteria interacting via surface contact with metal/oxides without the intervention of metal-ions.
