The scope of nanotechnology in the field of chemistry offers many applications and one of major applications is the synthesis of metal and metal oxide nanoparticles in the green manner. Copper (Cu) is nontoxic and have many medicinal and other importance. It is a cheaper and good antibacterial and antifungal agent and widely used in the catalytic and sensors. Various methods have been reported in literature for the synthesis of copper nanoparticles (CuNPs). The biological/green methods taking

... rt the copper salt and plant extracts are more efficient, very low cost and better alternatives over such methods. The chacterisation methods used for analysis of CuNPS are very important in the evaluation of their functional aspects. The common characterization techniques are Fourier transform infra-red (FTIR) spectroscopy, UV-Visible spectroscopy (UV-Vis), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffractometry (XRD), Dynamic light scattering (DLS) etc.
