Prasad S. Kshirsagar* and Darshana S. Mote

ABSTRACT

Objectives: The green synthesis of nanoparticles having eco-friendly approaches and generating interest & scope for researchers so present study focusses on the green synthesis of stable copper nanoparticles. Methods: This method involved preparations of leaf extract of Mentha Spicata in double-distilled water which act as a bioreducing agent. This synthesis involved addition of reducing agent to Cuso4 solution at different maintained temperature by using hot plate with magnetic stirrer. Result: During addition visual color change is observed from light sky blue to dark reddish-brown indicates the formation of the Copper nanoparticle. Prepared Nanoparticles were characterized using U.V visible spectrometry, Fourier transforms infrared spectroscopy (FTIR), X-Ray diffraction (XRD) and Transmission Electron Microscopy (TEM). Conclusion: Mentha Spicata leaf extract reduce the copper ions into copper nanoparticles within 25-30 minutes of time interval. By using this green synthesis there is a rapid, stable, eco-friendly synthesis of copper nanoparticles achieved.
