Production of AgNPs in unprocessed leaf extract and their identification by UV-Vis spectroscopy, Diffraction, and transmission electron microscopy | Original Article

ABSTRACT:

There is a low-cost and environmentally friendly alternative to conventional nanoparticle synthesis that can be obtained from plant extracts. The present paper reports the reduction of silver ions with extracts from Emblica officinalis, and Eucalyptus hybrida, resulting in stable, homogeneous silver nanoparticles. Silver nanoparticles can be obtained by this straightforward method in a short amount of time, making it of interest to scientists around the world. Various techniques, including UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), and energy diffraction Xray (EDX) analysis, were used to determine that the silver nanoparticles range in size from 20 nm to 80 nm and have a variety of shapes and sizes. Using X-ray diffraction, researchers found that the nanostructures had a crystal structure characteristic of a face-centered cubic. The presence of an absorption peak in UVVis spectra is evidence that they are manufactured. The development of a safe and environmentally benign method for the biological synthesis of metallic nanoparticles is a major step forward in the realm of nanobiotechnology's practical applications. Because of their biogenic nature, silver nanoparticles (Ag-NPs) may show to be a more effective medication option. Antibiotic resistance has spread at a frightening rate due to careless usage of the drugs. Ag-NPs have the potential to provide a one-size-fits-all answer to this pressing issue.
