Chandran M, Yuvaraj D, Christudhas L and Ramesh KV

Biosynthesis of metal nanoparticles using plants is currently focal point in nanomaterial studies. Green synthesis of metal nanoparticles has an important role to play in the future of medicine. This research paper focuses on the utilization of seaweed for the biosynthesis of iron nanoparticles in ambient conditions without any additives. The brown seaweed Dictyota dicotoma, was collected from the Muttom region in Kanyakumari district and utilized for the synthesis of iron nanoparticles. The NPs were characterized by UV-Visible spectrophotometer and FTIR. The nanoparticles produced were in the size range between 40 nm-50nm which was confirmed from the SEM analysis. The magnetic properties of the NPs were studied. The antimicrobial potential of the synthesized NPs were also evaluated. Nanoparticles coupled with antibiotics showed a greater inhibitory effect than the antibiotic and the synthesized nanoparticle’s individual performance.
