Biosynthesis and biophysical elucidation of CuO nanoparticle from Nyctanthes arbor-tristis Linn Leaf.

Copper oxide nanoparticles (CuO NPs) synthesis using an environmentally benign approach, as well as their antibacterial properties. Copper sulphate pentahydrate (CuSO.5HO) of different concentrations (2 mM, 5 mM and 10 mM) and aqueous Nyctanthes arbor-tristis leaf extract were used to make the CuO NPs.
