Abstract: The green synthesis of copper nanoparticles (Cu NPs) using a leaf extract from Parthenium hysterophorus has been documented in our present research work. The existence of flavonoids, tannins, glycosides, and alkaloids was confirmed by the phytochemical analysis of the plant extract and these chemicals can be used as reducing, stabilizing and capping agents. The Cu NPs were characterised by TEM and UV-vis spectrophotometry. The average sizes of the nanoparticles are found between 5-50nm indicating the effective reducing activity of plant extract and has many environmental applications.
