Purpose: To synthesize the copper nanoparticles Cu-Nps ,and to find the anti microbial activity of the plant “Hemigraphis colorata”.

Aim & objective: The aim of this research work was to synthesize g-Cu NPs mediated by Hemigraphis colorata medicinal plant leaf extract. The integration of bioactive compounds of this medicinal plant with Cu NPs is believed to be extremely beneficial for varieties of ailments. The biogenically synthesized g-Cu NPs were characterized using UV-visible,FT-IR,XRD,SEM,TEM and EDAX techniques. The antimicrobial properties of g-Cu NPs have also been evaluated against gram-positive and gramnegative bacteria.

Methodology: Hemigraphis colorata (or) murikooti is a postrate herb with rooting branches, deep reddish leaves and white flowers. It belongs to the family Acanthanceae. The leaf was collected from the medicinal garden. Leaf was extracted for the synthesis of nanoparticles. The characterization of nanoparticles were noted (UV-vis, FT-IR,XRD,SEM TEM,EDAX).The microbiological activity of the leaf is noted.

Results and discussion: The green synthesis Cu NPs were synthesized by using copper sulphate as a precursor and plant leaf extract as a reducing and capping agent. The change in color from blue to light brownish visually indicates the formation of copper NPs. The Cu NPs were washed by demonized water and ethanol to remove any unwanted particles.
