Biosynthesis and characterization of copper nanoparticles using fresh aqueous Ziziphus spina christi (L.) extract

The synthesis of metal nanoparticles is a growing area for research due to its potentiality in the application and development of advanced lechnologies. In general, nanoparticles are synthesized by using chemical methods which are not eco-friendly. In this study we used the fast, convenient, eco-friendly method for synthesis of copper nano particles by using the fresh ziziphus spina Christi (L.) (Zscl) extract. The fresh aqueous Zscl extract was mixed with copper sulphate solution by heating to temperature of 60-80˚, The reduction reaction was studied by observing the color change from blue to reddish brown, Water soluble antioxidant consituents present in the fresh aqueous ZscL extract were mainly responsible for the reduction of copper ions to nano sized Cu particles. The resulting copper nanoparticles were characterized by UV-Vis absorption spectrometer, X-Ray diffraction (XRD), fourier thransform infrared (FTIR) and transmission clectron microscopy (TEM).
