Synthesis of Rosemary Oleoresin Mediated Silver Nanoparticles and its Characterisation Using UVVis Spectrophotometry and TEM.

Abstract

Preparation of nanosized silver based materials, is amongst the most emerging areas in the field of
nanotechnology. Green synthesis of silver nanoparticles using different plant extracts and its resources are
received many appreciation due to its environment al friendly capping and reducing properties. In this
study, silver nanoparticles were synthesised using rosemary oleoresin. The synthesised nanoparticles
were confirmed using UV-spectrophotometer and the size and shape were characterised by Transmission
electron microscope. TEM analysis showed the size of silver nanoparticles from 10 – 25 nm. In conclusion,
the reduction of the silver nitrate ion through rosemary oleoresin important to the formation of silver
nanoparticles with so much of economic viability and valuable.
