Green Synthesis of Copper Nanoparticles Mediated By Dioscorea Bulbifera Tuber for Biofilm Inhibition
Keywords:
Green synthesis, copper nanoparticles, Dioscorea bulbifera, biofilm and Candida albicansAbstract
Herein, we report the synthesis of Cu NPs via green approach using Dioscorea bulbifera plant tuber extract. The as-synthesized products were characterized using X-ray diffraction (XRD) analysis reveals that confirmation of the face centered cubic (FCC) crystal structure without any impurity peaks with a lattice constant 0.3620 nm. Fourier Transform Infrared Spectroscopy (FTIR) shows the components like flavonoid and phenol were observed, which have contributed as surface capping agents for NPs. UV-visible spectroscopy shows that Cu NPs shows a strong surface Plasmon resonance absorption peak at 570 nm, which attributed to the formation of Cu NPs. Field emission scanning electron microscope (FE-SEM) exhibit a spherical shape of Cu NPs agglomerate morphology and Energy Dispersive X-ray analysis (EDAX) which confirm the presence of only Cu element without any impurities. Synthesized sample explored of Candida albicans biofilm and it shows about 20 % inhibition of biofilms.
