Abstract

Natural polymer (Pectin) was used to synthesize the silver nanoparticles (SNPs) in a spontaneous way without
using any reducing agent. SNPs have been obtained by the mixing of various amounts of silver nitrate with 2%
of aqueous pectin. The formed nano silver-pectin solutions were caused to get the nanocomposite thin films.
The formation of SNPs have been characterized by ultraviolet-visible (UV-vis), Fourier transform infrared,
and transmission electron microscopy (TEM) analyzes. The formation of SNPs confirmed by a characteristic
absorption peak at 420 nm obtained from UV-vis spectrum. The average particle size SNPs was examined by TEM,
i.e., 10 nm. The synthesized SNPs were evaluated for an antibacterial activity toward Bacillus and Escherichia
coli, the result suggested that they are high potent in nature. The potentiality of this method is which it is possible
to prepare SNPs without any synthetic reducing agents. Hence, it is environmentally safe and has a promising
potential future in the medical or pharmaceutical area.
