Iron oxide nanoparticles (NPs) are gaining importance for their uses in environmental remediation technologies. In the present investigation FeO NPs were synthesized by colonial tunicate Ecteinascidia venui. FeO NPs were generated by reaction of ferric chloride (FeCl3) solution with tunicate extracts. The reductants present in the tunicate extracts act as reducing and stabilizing agent. Synthesized NPs were characterized using FTIR, UV-Vis absorption spectrophotometer, XRD and SEM. FT-IR measurement was carried out to identify the possible molecules like CO, CH, OH band. UV-Vis absorption shows a characteristic absorption peak of iron oxide NPs in the range of 190-250 nm. From the XRD, it was found that the average particle size of magnetite NPs was found to be 111 plane. SEM image shows agglomerated structure. AFM and Redox potential show the nature of iron oxide NPs and applications of iron oxide NPs predicts the better antioxidant activity. This biosynthetic approach is cost effective, eco-friendly and has promising valuable applications in medicine.
