Electrodeposition of antibacterial Zn-Cu/silver nanoparticle (AgNP) composite coatings from an alkaline solution containing glycine and AgNPs

Antimicrobial tests performed on the Zn-Cu/AgNP composite coatings against the microorganisms Escherichia coli as a model gram-negative bacteria and Staphylococcus aureus as a model gram-positive bacteria revealed 95% to 100% inhibition of bacterial growth after 10 min of contact for the Zn-Cu/AgNP coating with a AgNP content of 0.28 wt%.
