A Review on Silver Nanoparticles: A Green Synthesis and their use

An emerging field of nanotechnology that provides benefits over chemical and physical synthesis methods in terms of cost and environmental friendliness is the biological production of nanoparticles. Consequently, scientists attempted to biosynthesize the nanoparticles using biological sources in an effort to lessen their harmful effects. Researchers are concentrating on marine resources since these resources are renewable and accessible year-round. In most cases, the stability and morphology of the seaweed-derived nanoparticles for use in medicinal and environmental applications are comparable to those of other "green" processes. Since nanotechnology may be used practically wherever, it represents an expanding field in medical science. Phytoconstituents are promising and valuable sources for the synthesis of green silver nanoparticles, or AgNPs, which have enormous potential in treating chronic illnesses. Numerous analytical techniques are used to analyse AgNPs, such as SEM, FTIR, XRD, DLS, TEM, and UV-visible spectroscopy. Owing to its many applications, it has been utilized in wound dressing, diagnostics, orthopaedics, the food industry, home, and medical equipment, as well as anticancer anti-bacterial, anti-fungal, and other uses. This article gives an overview of the environmentally friendly process for producing and characterising AgNPs. This research therefore discusses seaweeds as a better way to make metal nanoparticles.
