Optimization, characterization of silver nanoparticles from the young leaves of Pancratium telanganense and application studies against pathogen bacteria

Abstract

Optimization of nature friendly and consistent developments of the green synthesis of nanoparticles have engrossed encouraged in nanotechnology since of its marvelous incentive in modifying metals into nano size to its probable use for human welfares. The present report reveals the young leaves of Pancratium telanganense was exposed for extra-cellular bio-synthesis of silver nanoparticles (AgNPs) and its antibacterial actions against bacterial pathogens The eco-friendly biosynthesized AgNps optimized then considered by UV spectrum, FTIR, TEM. Then formed AgNPs were confirmed against bacterial test organisms. The young leaves of Pancratium telanganense were establish to be a noble fabricator of AgNPs. Expansion maximizes exhibited absorbance of 420–425 nm at pH-7, 25 °C with 1 mM AgNO3 concentration and 100 mg of leaves powder crude extract. Auxiliary TEM discovered the types of formation of irregular, fine discrete nanoparticles with size ranging between 20 to 35 nm, the FTIR illustrations the bands at 1644 and 153 8 cm−1 consistent to the necessary ambiances of bands of proteins. Antibacterial activities against bacterial pathogens exhibited good results have shown the maximum inhibition zone about 18 mm and 17 mm respectively at 60 μl of AgNps.
