The plant has been used traditionally for ages, in the treatment of urogenital disorders, piles, dysentery, sinus, and also applied on wounds. In current study, ethanolic extract of Mimosa pudica was used for the synthesis of copper nanoparticles. The formation of copper nanoparticle was confirmed by UV-Visible spectroscopy. Fourier Transform Infra red Spectroscopy (FTIR) revealed the possible involvement of photo-constituents in copper nanoparticles of crude extract.XRD is commonly used to determine the chemical composition and crystal structure of a material. Further Transmission Electron Microscopy (TEM) was used for the shape and morphology determination. The bio-synthesized copper nanoparticles were found to be effective against pathogenic bacterial and fungal strains. The in-vitro cytotoxicity activity of copper nanoparticles was performed against MCF-7cell line (breast cancer cell line) and compared against the vero cell line (normal cell line). The result showed that the copper nano particles show moderate activity against the cancer cell but seems to have less toxicity towards normal cell.
