Magnetic Decoupling of Surface Fe3+ in Magnetite Nanoparticles upon Nitrocatechol-Anchored Dispersant Binding
Bind and distort: NitroDOPA, an anchor shown to irreversibly couple dispersants and functional groups to superparamagnetic Fe3O4 nanoparticles, can magnetically decouple Fe3+ in a nanoparticle surface layer. The strong binding of nitroDOPA distorts the Fe3+ ligand field. This ESR finding sheds light...
