HIGH STABILITY THIOL-COATED GOLD NANOSTARS MONOLAYERS WITH PHOTO-THERMAL ANTIBACTERIAL ACTIVITY AND WETTABILITY CONTROL

High Stability Thiol-Coated Gold Nanostars Monolayers with Photo-Thermal Antibacterial Activity and Wettability Control

The adhesion and proliferation of bacteria on abiotic surfaces pose challenges in both health care and industrial applications.Gold nanostars (GNSs) monolayers grafted on glass have demonstrated to exert antibacterial action due to their photo-thermal features.Here, these GNS layers were further functionalized using thiols monolayers, in order to i
