Bioinspired photocatalytic ZnO/Au nanopillar-modified surface for enhanced antibacterial and antiadhesive property
Abstract(#br)Biological contamination of surfaces is a thorny issue that brings series of adverse factors to the daily life and industrial manufacture. A dragonfly-wing-mimicking nanopillar array of ZnO/Au on Polydimethylsiloxane (PDMS-ZnO/Au) with two-fold bactericidal activity as well as the antiadhesive property has been developed. In this process, ZnO nanopillar is obtained using a hydrothermal method followed by the introduction of plasmonic gold nanoparticles (AuNPs) via a photo-reduction protocol.
