Biological fouling has caused a lot of concern owing to their concerns in marine industries. The attachment of microorganisms including bacteria, algae and diatoms on a marine surface to create a biofilm causes negative impacts on the marine industry such as an increase in weights of hulls, low speed, and high fuel consumption. In the recent past, nanoparticles have attracted a lot of attention in the fields of material science, chemistry and biology owing to their rare biological properties. Silver nanoparticles (AgNPs) have been long known for its strong toxicity against a wide range of microorganisms. Herein, we synthesized the AgNPs via green synthesis approach known for its benefits such as one-pot, inexpensive and eco-friendly; by using Illicium verum (IV) extract as demoting and sustaining agent. Further, characterization tests of obtained AgNPs-IV were investigated including by UV-Vis, FTIR, XRD, SEM, TEM, AFM, and particle size distribution. The Uv-Vis result confirmed the AgNPs-IV formation with its surface Plasmon resonance peak. FTIR was tested to investigate the bio-functional groups liable for the AgNPs-IV synthesis. XRD peaks also meet with the standard of AgNPs (JCPDS: 41-1402). SEM, TEM and AFM analysis of AgNPs-IV showed the hexagonal structure with 14.56 nm mean size. The green synthesized AgNPs-IV showed excellent antidiatom activity against Paeodactylum Tricornutum marine diatom.
