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.
