INTRODUCTION: Development of green nanotechnology is generating interest of researchers toward ecofriendly biosynthesis of nanoparticles. Nanoparticles serve to be a bridge between bulk materials and atomic/ molecular structures and are of great interest because of their excellent physical and optical properties. The aim and objective of the present study is to synthesize copper nanoparticles using dried ginger and its characterization by UV-vis spectroscopy and TEM. MATERIALS AND METHOD: For this study, “Zinigiber officinale” (ginger) was collected, dried and extracted. 30 ml extract was mixed with 0.507g of copper sulphate (anhydrous) was and 70 ml of distilled water. The solution was observed to be light blue in colour. Then the product was dried and heated in the furnace. RESULTS: From the synthesised nanoparticles using dried ginger, the change in colour was recorded in intervals of every 1 hr and There was a colour change from bright blue to light blue. This was characterised using UV vis spectroscopy and transmission electron microscopy. CONCLUSION: This was cost efficient and eco friendly compared to other methods. The use of toxic reagents were avoided and are pollution free.
