Fabrication of antibacterial surface via UV-inducing dopamine polymerization combined with co-deposition Ag nanoparticles

• Antibacterial surface was fabricated by a simple one-step co-deposition process.
• The modified substrates showed excellent antibacterial property.
• The study affords an efficient method for the fabrication of antibacterial surface.

In this study, a simple one-step co-deposition process was introduced to fabricate antibacterial surfaces for synthetic materials via UV-inducing dopamine polymerization combined with in situ formation of Ag nanoparticles. The successful formation of a composite coating was demonstrated by scanning electron microscopy. Antibacterial experiments including antibacterial rate test and bacteria adhesion were evaluated in vitro. The results confirmed the excellent antibacterial property of this surface modification process. In conclusion, the approach presented here provides a simple and effective approach to construct antibacterial surfaces for synthetic materials to meet the requirements of daily life and industry application.
