Combining iron oxide nanoparticles (Fe3O4 NPs) and gold nanoparticles (Au NPs) in one nanostructure is a promising technique for various applications. Fe3O4 NPs have special supermagnetic attributes that allow them to be applied in different areas. and Au NPs stand out in biomaterials due to their oxidation resistance. chemical stability. https://www.hindigyanvishv.com/
