GREEN SYNTHESIS OF COPPER NANOPARTICLE FROM PASSIFLORA FOETIDA LEAF EXTRACT AND ITS ANTIBACTERIAL ACTIVITY
Objective: Development of green nanotechnology is generating interest of researchers toward eco-friendly biosynthesis of nanoparticles (NPs). In
this study, biosynthesis of stable copper (Cu) NPs was done using Ocimum sanctum leaf extract.
Materials and Methods: First, we prepared leaf extract of Passiflora foetida in deionized water. This extract added to 20 mMol of Cu sulfate solution,Â and we observed the change in color of the solution from colorless to colored solution; this indicates that there is a formation of CuNPs.
Results: These biosynthesized CuNPs were characterized with the help of ultraviolet visible spectroscopy, X-ray diffraction, and Fourier transformÂ infrared spectroscopy. The spectroscopic analysis of synthesized CuNPs showed the maximum absorbance at 350 nm indicating the presence ofÂ biosynthesized CuNPs in the reaction mixture.
Conclusion: It was observed that the P. foetida leaf extract can reduce Cu ions into CuNPs within 8-10 minutes of reaction time. Thus, this method can
be used for rapid and eco-friendly biosynthesis of stable CuNPs.
