[en] In view of the immense capability of plants this work is planned to employ seed extract as a source for the reduction of Cuions in to Cu nanoparticles (Cu NPs). For this purpose seed extract of Trigonella foenum-graecum (fenugreek seeds) was utilized as a substitute of classical methods. This green path for synthesizing Cu NPS is easy, natural, low cost, sustainable and eco-friendly as compared to conventional methods. In this experiment harmful chemical/physical methods for the production of Cu nanoparticles is replaced by using minimum concentration of seed extract. The stepwise characterization was done by using Atomic Absorption spectroscopy, UV-Vis Spectroscopy, FTIR spectrophotometer and X-ray diffraction (XRD) which have given much valuable information about these materials. Antibacterial activity of these nanoparticles is observed at different concentration so their ZOI (Zone of inhibition) and MIC (minimum inhibitory Concentration) was also calculated against four human pathogenic strains.
