Abstract

Bacterial infection is a major problem in our society because some diseases originate from various microbes. Therefore, much research has been devoted to the design and engineering of novel nanomaterials with improved functionality for bacterial disinfection. In this regard, noble metal and metal oxides such as silver (Ag) and titanium dioxide (TiO2) nanostructures, respectively, have shown great potential in the field of nanobiotechnology for antibacterial applications because of their unique optical properties. Furthermore, coupling of these nanomaterials has shown promising effects extending their applicability in solar light with enhanced photo-induced antibacterial properties. The present chapter reviews recent progress in novel functional Ag-TiO2 nanocomposites for their antibacterial applications with special emphasis on their mechanisms and real practical applications.
