Synthesis of gallotannin capped iron oxide nanoparticles and their broad spectrum biological applications.

ABSTRACT: Green synthesized nanoparticles (NPs) have attracted enormous attention for their clinical and non-clinical applications. A natural polyphenol, gallo-tannin (GT) was used to reduce and cap the Fe₂O₃-NPs. GT-Fe₂O₃-NPs were synthesized following co-precipitation of FeCl₃ and FeSO₄·7H₂O with GT. Fe₂O₃-NPs absorbed light at 380 nm. Physicochemically, Fe₂O₃-NPs were spherical with slight aggregation and average diameter of 12.85 nm. X-ray diffraction confirmed crystallinity and EDX revealed the elemental percentage of iron and oxygen as 21.7% and 42.11%, respectively. FT-IR data confirmed the adsorption of gallo-tannin functional groups. Multiple drug-resistant (MDR) Esche
