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 Fe 3O 4 nanoparticles, can magnetically decouple Fe 3+ in a nanoparticle surface layer. The strong binding of nitroDOPA distorts the Fe 3+ ligand field. This ESR finding sheds light on an important binding mechanism of anchors used for nanoparticle surface modification (see graphic).
