Abstract EN
A single-step environmental friendly approach is employed to synthesize silver nanoparticles.
The biomolecules found in plants induce the reduction of Ag+ ions from silver nitrate to silver nanoparticles (AgNPs).
UV-visible spectrum of the aqueous medium containing silver ions demonstrated a peak at 425 nm corresponding to the plasmon absorbance of silver nanoparticles.
Transmission electron microscopy (TEM) showed the formation of well-dispersed silver nanoparticles in the range of 5–20 nm.
X-ray diffraction (XRD) spectrum of the AgNPs exhibited 2θ values corresponding to the silver nanocrystal.
The process of reduction is extracellular and fast which may lead to the development of easy biosynthesis of silver nanoparticles.
Plants during glycolysis produce a large amount of H+ ions along with NAD which acts as a strong redoxing agent; this seems to be responsible for the formation of AgNPs.
Water-soluble antioxidative agents like ascorbic acids further seem to be responsible for the reduction of AgNPs.
These AgNPs produced show good antimicrobial activity against common pathogens.
