Review on Plant Mediated Green Synthesis of Magnetite Nanoparticles for Pollution Abatement, Biomedical and Electronic Applications

In nature, the iron oxide is found in various forms. It is chemically mixed to form iron oxides(compounds). Magnetite has helpful uses in different areas, such as medicinal carriers, MRI-contractingagents, tumour therapies, industrial, laboratory dyes adsorption and wastewater treatment of toxicmetals such as mercury and arsenic. Magnetic iron oxide nanoparticles are generated using variousmethods such as wet, dry or microbiological processes. The drawbacks of conventional nanoparticlesincluding attrition and pyrolysis include a defective surface formation, poor efficiency rates, highdevelopment costs and high energy consumption. The first approach is the green biosynthesis of thenanoparticles in which the metal atoms are clusters. The organic compounds can both minimize andcover nanoparticles in the process of synthesis in green materials. In recent years, nanocarriers, especiallyfor poorly soluble medicines, have received growing attention for oral chemotherapy. Early diseasebacteria, biopsy, cells, DNA, glucose and viruses are identified by biosensing. While several basiccharacteristics have different advantages and potential for biomedical use of magnets of iron oxides,more toxicological research is required on as-synthesized magnet iron oxide nanoparticles with clearlydefined requirements for toxicity assessment.
