ECOFRIENDLY GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES FROM ROOT EXTRACT OF ......

The goal of this work was to create silver nanoparticles from the aqueous root extract of Echinops kebericho in a quick and easy way. Both lowering and capping abilities were demonstrated by the root extract. FTIR was used to examine the key chemicals involved in the manufacture of silver nanoparticles. The UV–Visible spectrometer and TEM were used to characterise the nanoparticles that were produced. Nanoparticles with an average size of 34 nm were discovered using TEM. A peak in the range of 420–435 nm was observed using a UV–Visible spectrometer. Antibacterial activity was observed against both Escherichia coli (gramme negative) and Staphylococcus aureus (gramme positive) bacteria in antimicrobial experiments using silver nanoparticles. An increase in the plant extract resulted in a considerable increase in flavonoid and phenolic components. Antioxidant activity as measured by DPPH showed that plant extract reduced DPPH. The total finding implies that silver nanoparticles may be synthesised in less than 15 minutes. Furthermore, the absence of any chemical in the nanoparticles' creation makes them non–toxic, environmentally benign, and a viable alternative to traditional physical/chemical procedures.
