Cajanus Cajan Mediated Gold Nanoparticle Synthesis, Characterization, Antimicrobial efficacy and its Antifouling Application on Metal Coupons


Vidhya Ananthi T*, Ahmed John S

The present study is focused on the biosynthesis of AuNPs using Leaf extract of Cajanus cajan and its characterization through UV-Vis Spectrophotometry, Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), DLS – Size Distribution and Zeta potential and biofilm accumulation analysis by Epi – Florescence Microscopy. The ability of the green synthesized Gold Nanoparticles to control/prevent the biofilm forming bacterial communities (which were considered as primary colonizers) was analysed by conducting the antimicrofouling studies. The Gold Nanoparticles were found to control the growth and survival of biofilm forming bacteria effectively on SS304 metal coupons. The present work gives scope for the possible development of formulations containing AuNps as effective antifouling agent that could prevent microfouling, thereby preventing marine biofouling.
