The Ag:O atomic ratio was tailored during the pulsed laser deposition process by adjusting the O2 environment, and thus, a wide range of silver oxide phases ranging from Ag to AgxO was achieved. Simultaneously, the morphology was controlled from island-like (Volmer–Weber) formations to nanoparticle arrays, ultimately culminating in cauliflower-like dendrite structures.Through this synergistic approach, enhancing the oxygen content while expanding the active surface area yielded optimal enhancement of the antimicrobial properties. Remarkably, films deposited at elevated O2 pressures exhibited heightened inhibitory effects against bacterial biofilms, with films featuring nanoparticle morphology demonstrating notable antistaphylococcal efficacy.
