Abstract
Nanotechnology is a rapidly developing scientific discipline with promise for enhancing human well-being via its applications in nanomedicine. It describes the technology used to accurately manipulate atoms and molecules to create new materials with dimensions that are on the nanoscale. The usual size range of nanoparticles (NPs) is 1-100 nm. Since nanoparticles are important in preventing infections, they can be used as therapeutic nanocarriers having antibacterial properties. This paper reviews the literature on the various production techniques, characteristics, and biological uses of several nano-metal oxides (iron oxide, titanium dioxide, zinc oxide, and cadmium oxide). The utilization of nanoparticles and their applications will grow due to the cost-effective ways available for biomodification. Because of their special qualities, nanoparticles are helpful in several scientific domains, including biology, materials science, engineering, electronics, and food science. Researchers have become interested in nanotechnology because of its benefits, particularly its potential uses in the healthcare system for improved diagnosis and treatment.
