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

Preparation of nanosized silver based materials, is amongst the most emerging areas in the field ofnanotechnology. Green synthesis of silver nanoparticles using different plant extracts and its resources arereceived many appreciation due to its environment al friendly capping and reducing properties. In thisstudy, silver nanoparticles were synthesised using rosemary oleoresin. The synthesised nanoparticleswere confirmed using UV-spectrophotometer and the size and shape were characterised by Transmissionelectron 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 silvernanoparticles with so much of economic viability and valuable.
