Synthesis of Silver Nanoparticles from Plant and Fruit Extracts- Summary on Research and Studies

Abstract

Nanoparticles can be synthesized by various methods such as gas condensation, attrition, chemical precipitation, pyrolysis and hydrothermal synthesis. These nanomaterials find application in paint and pigment industry, electrical equipments and chemical processing industries. The enhancement of heat transfer coefficient by nanofluids is also widely discussed and investigated research area. Carbon nanotubes are used in antenas. They also find application in selective removal of some pollutants by adsorption. The high surface to volume ratio makes them highly catalytic and reactive. Synthesis of the nanoparticles can be carried out by various physical, physic chemical and biological methods. Current review summarizes research and studies on synthesis of silver nanoparticles from plant extracts. Silver nanoparticles are finding importance because of wide range of applications due to unique optical, electrical, and thermal properties. High electrical conductivity, stability, and low sintering temperatures are some important features of nanoparticles.
