Zingiber officinale Extracted Green Synthesis of Copper Nanoparticles: Structural, Morphological and Antibacterial Studies
The Zingiber officinale (Z. officinale) plant is one of the well-known medicinal plants. Copper nanoparticles (CuNPs) were synthesized successfully by a simple green route using Z. officinale extract. CuNPs are known to be one of the multifunctional inorganic nanoparticles
with effective antibacterial activity. The influence of the size of CuNPs on antibacterial activity was studied. The morphology and structure of the synthesized CuNPs were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, transmission electron
microscopy (TEM), energy dispersive X-ray (EDX) spectra and selected area electron diffraction (SAED) analysis. The formation of face-centered cubic (fcc) structure CuNPs was confirmed by XRD results. The average crystallite size of CuNPs was found to be 10.13 nm. The EDX spectra shows
the elemental composition of CuNPs and it was confirmed the formation of CuNPs without other impurities. The anti-bacterial activity of CuNPs has been investigated using three pathogens Escherichia coli, Klebsiella pneumonia and Staphylococcus aureus. Poloxamer finds excellent
clinical and therapeutic uses for curing of various ailments. The poloxamer 188 protected CuNPs inhibit the bacterial growth more effectively than the pure Z. officinale extract and the Z. officinale extract CuNPs.
