Roy N, Barik A (2010) Green Synthesis of Silver Nanoparticles from the Unexploited Weed Resources.

Silver nanocubes were synthesized for the first time in large quantities on gold seed in the presence of a polyelectrolyte using microwave heating for 60-120 s. Our experiment indicates that the polyelectrolyte directs the growth of the particle in a specified crystallographic direction resulting in the faceted particle, i.e. a nanocube. The nanocubes are stable for at least 2 months in ambient conditions.

N2 - Silver nanoparticles are synthesized by the reduction of metal salt solutions from sodium borohydride in a microfluidic chip. The influence of different operating conditions on silver particle diameter, morphology, size distribution, and elemental compositions has been investigated. The results demonstrated that ethylenediaminetetraacetic acid (EDTA) serving as a complexant significantly affected the particle size of synthesized silver nanoparticles. An increase in the silver nanoparticle mean diameter was observed with decreasing NaBH4/AgNO3 molar concentration ratios, and increasing fluid flow rates.

ABSTRACT: In our present study the conventional (physical and chemical) method of nano particles synthesis was replaced with biological synthesis of silver nanoparticles by using the leaf extract of Wrightia tinctoria. New drug delivery system has been enhanced with noval techniques like nano particle synthesis and its role in drug delivery system, by exploiting the nanotechnology in particle synthesis. The aqueous extract of Wrightia tinctoria leaves was prepared and mixed with 1mM AgNO3 solution. After 48 hours the reduction of silver nitrate to silver nanoparticles (AgNPs) was confirmed by UV-visible spectrophotometer. The size of Silver nanoparticles were characterized by XRD and FTIR and the size were of 19 – 68nm. The biosynthesis of AgNPs using Wrightia tinctoria leaf extract is very simple and economic. This green chemistry approach is amenable to large scale commercial production. The use of environmentally benign and renewable plant material offers enormous benefits of eco-friendliness. Key words: Wrightia tinctoria, silver nano particle synthesis, FTIR, XRD,

The reaction used for the synthesis of silver nanoparticles is the ..

Forming an ordered surface layer is possible together with the formation of Janus nanoparticles in the chemical modification of the surface of silver colloids. This is achieved via sorption of nanoparticles on the surface of chemically modified silica grafted with amine, followed by sequential treatment with modifier solutions and desorption of the final product. As a result of using such a synthetic procedure, a chemical modification of nanoparticles with two compounds on different sides is possible.
