Physicochemical And Microbial Insights Of Doped Metal Oxide Nanoparticles For Optical And Biological Applications

Abstract

Nanomaterials have unique physicochemical characteristics which may differ from their bulk counterparts. In recent years, the revolutionary nanotechnology has been applied to many fields with an integrated approach. Thus, the nanotechnology plays an important role in the production of novel materials and significant applications through the preparation and characterization of various nanoparticles (NPs). NPs provide novel prospects of commercial and scientific applications. Among these NPs, metal oxide nanoparticles (MONPs) such as zinc oxide (ZnO), cupric oxide (CuO), and magnesium dialuminium oxide (MgAl2O4) nanoparticles have attracted particular attention in technological and scientific fields because of their interesting structural, mechanical, physical, optical, chemical, electrical, magnetic, catalytic, and morphological properties. MONPs are the most commonly used nanomaterials (NMs) and particularly, transition metal oxide (ZnO and CuO) nanoparticles are technologically important materials and have received much attention in the fields of magnetic storage devices, sensors, optoelectronics, electrodes of lithium-ion batteries, light-induced catalysis and biomedical applications due to their size and morphology dependent functional and physicochemical properties. Magnesium dialuminium oxide (MgAl2O4) nano-powder materials with high mechanical strength have a variety of potential applications in chemical, metallurgical, electro technical, electronic, biomedical, and catalysis industries because of having excellent thermal, optical, biological and chemical properties. Hence, significant research work is being carried out in the fabrication of nanomaterials with various desired properties which could be achieved by changing the parameters, including the dopants, surfactants, and solvents to address the biological and environmental issues in order achieve the sustainable development. With this desired motivation, pure and sodium doped ZnO; undoped Andhra University, Visakhapatnam Page | ix and sodium doped CuO
