Light-Activated Nanoparticles for Antibacterial Studies

Abstract

Photolysis or light activation of electrons to an energy excited state to aid a release of energy could be utilized in many applications like industries and semiconductors as well as for antimicrobial action. This electron transfer mechanism is widely being incorporated to metals and metal oxides or sometimes with nanoparticles (NPs) to increase its reactivity. However, three forms of NP formulations are used for antibacterial action like nanocomposites, doped NPs, and metal oxide NPs. The preparation, synthesis, and antimicrobial application of the metal oxide NPs are explained coherently in this chapter. Moreover, the future prospects of these NP-assisted light-activated antimicrobial actions are also dealt in detail.
