In the present study green synthesis of magnetic nanoparticles has been described. Green tea was used in the synthesis of these nanoparticles due to its reducing property. The surface of green tea-magnetic nanoparticles was modified with tetra ethyl orthosilicate for silica coating, and further silica-coated green tea-magnetic nanoparticles were amine-activated by (3-aminopropyl)triethoxysilane. The proposed work is simple and cost-effective. Characterization of the structure and composition of green synthesized magnetic nanoparticles was formulated by X-ray diffraction analysis, Fourier transform-infra red, scanning electron microscope, electron dispersive X-ray and high-resolution transmission electron microscope.
