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.
