Abstract :
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.
