Meteoric synthesis of Luminescent Fe2O3 Nanoparticles: A potential Cytotoxic, Antioxidant & Bactericidal agent

Here we report the meteoric synthesis of luminescent nanomagnetic Fe2O3 (LNM Fe2O3) particles using green sources ie, microwave energy of 800 W and Hibiscus rosasinensis (H rosasinensis) leaf extract with high anti oxidant and anti cancer properties as an active surfactant. The microwave irradiation times for the synthesis of LNM Fe2O3 particles were optimized. Structural morphology, magnetic and optical properties of synthesized LNM Fe2O3 particles was studied using different analytical techniques. The data clearly indicated that H rosasinensis leaf extract‐mediated LNM Fe2O3 particles are spherical in shape with the presence of both α‐Fe2O3 and small amounts of ϒ ‐ Fe2O3 phases which have smaller size and larger surface area with slight agglomeration. Cytotoxic activities were performed on HCT‐116, HeLa and MCF‐7 cancer cell lines using MTT assay, antioxidant ability was determined using DPPH assay and bactericidal activity studies performed on Gram‐negative E coli bacteria and Gram‐positive bacteria Bacillus subtilis for the synthesized LNM Fe2O3 particles which were found to be highly efficient. Biological studies revealed that synthesized luminescent nanomagnetic Fe2O3 particles act as potential cytotoxic, antioxidant and bactericidal agent.
