Synthesis and Physicochemical Studies on Morphlinecarbamic Acid Capped Silver Nanoparticles
Journal Title: Journal of Biological and chemical Chronicles - Year 2018, Vol 4, Issue 1
Abstract
A systematic and detailed study for antibacterial efficacy of silver nanoparticles (AgNPs) synthesized with a passivating monolayer of morphlinecarbamic acid using a chemical reduction approach is presented here. As synthesized silver nanoparticles were obtained with good yield, monodispersity, high stability and crystallinity. These AgNPs were characterized by elemental analysis and energy dispersive analysis of X-rays (EDAX). SEM images of powdered sample revealed spherical shape with particle size 100-200 nm. XRD patterns indicated arrangement of silver nanoparticles with a face centered cubic (fcc) structure. A surface plasmon resonance peak was observed at 430nm. As synthesized silver nanoparticles were tested for antimicrobial activity against different pathogenic microorganisms such as Proteus vulgaris (Gram negative), Staphylococcus citrus (Gram positive) and Staphylococcus epidermidis (Gram positive). Silver nanoparticles with ligand metal feed ratio (1×1) showed prominent inhibition in activity towards S. Epidermidis with maximum zone of inhibition value of 14 ± 1.5 mm. Lipase activity of morphlinecarbamic acid capped silver nanoparticles showed reduction from 191.37 - 16.74 μmol/ml/min in activity with ligand metal feed ratio (1×1).
