Synthesis and Characterization of silver nanoparticles using Lablab purpureus flowers (Purple colour) and its anti-microbial activities
Keywords:
Green synthesis, Lablab purpureus, Silver nanoparticles, SEM, Antimicrobial propertyAbstract
In recent years, green Bio-synthesis of silver nanoparticles (AgNPs) has gained much interest from chemists and researchers. In this concern, Indian flora has yet to divulge innumerable sources of cost-effective, non –hazardous, reducing and stabilizing compounds utilized in preparing AgNPs. This study investigates an effective and sustainable route of AgNP preparation from 1 mM aqueous AgNO3 using extracts of Lablab purpureus flowers (purple colour) which are well adorned for their wide availability and medicinal property. The AgNPs were characterized by UV-visible (vis) spectrophotometer, Scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FTIR) analysis, and XRD. The AgNPs obtained from extracts significantly higher antimicrobial activities against staphylococcus aureus and E.Coli.in comparison to both AgNO3 and raw plant extracts. In totality, the AgNPs prepared are safe to be discharged in the environment and possibly utilized in process of pollution remediation. AgNPs may also be efficiently utilized in green research to obtain better health using crop plants as shown by our study.
