Cysteine-functionalized silica-coated magnetite nanoparticles as potential nanoadsorbents

Fe3O4@SiO2@ICPTES-cysteine nanoparticles have been synthesised through a four-step functionalization process: synthesis of Fe3O4 MNPs, coating with SiO2, functionalization with ICPTES, and the covalent grafting of cysteine onto these MNPs.295
