Abstract—Due to its cost-effectiveness and eco-friendliness, plant-mediated nano-material production has become more and more popular. An emerging area in nano-technology and nanoscience in former years is the green and environmentally acceptable technique of production for metal nano-particles. The majority of the uses for copper nanoparticles (Cu NPs) are in the fields of medicine, electronics, Biosensors, lubricants, reagents in various methods, and antimicrobial, antifungal, and antimicrobial compounds, among other things. In the current study, copper nitride nanoparticles (Cu NPs) were synthesized in an environmentally friendly and green manner utilizing Murraya koenigii (Curry leaves), Laurus nobilis (Bay leaves), Trigonella foenum graecum (Fenugreek leaves), Curcuma longa (Turmeric) leaf extract and a 1mM copper sulphate (CuSO4.5H2O) solution. Using the use of FTIR and UV-visible spectroscopy, the produced Cu NPs were evaluated. The current study's objective is to look into the phyto screening chemicals found in aqueous curry leaf, with the goal of determining their antibacterial activity. Tannins, saponins, alkaloids, quinones, terpenoids, cardio glycosides, and phenols were found in the aqueous leaf extract, according to the research.
