Electronic Thesis and Dissertation Repository

In this thesis, active and passive antimicrobial methods have been applied to fabricate antifouling surfaces. In the first study, we reported the synthesis and characterization of neat TiO₂ and Ag-TiO₂ composite nanofilms prepared on silicon wafer by sol-gel method. The synthesized Ag-TiO₂ thin films showed enhanced bactericidal activities compared to the neat TiO₂ nanofilm both in the dark and under UV illumination. The advantage of Ag-TiO₂ nano-composites is to expand the nanomaterial’s antibacterial function to a broader range of working conditions. In the second study, we reported the synthesis, characterization and environmental application of nitrogen …
