Journal of Electrochemistry
Surface molecularly imprinted magnetic nanoparticles (NPs) were prepared by employing dopamine (DA) as a functional monomer, hemoglobin (Hb) as a template, H2PtCl6 as an oxidant triggered DA polymerization on the surface of the Fe3O4 NPs. The Hb and the formed platinum nanoparticles (PtNPs) were embedded into the polydopamine (PDA). After removal of the Hb, the surface molecularly imprinted magnetic nanoparticles (imprinted Fe3O4/PDA-PtNPs) were formed, and then simply immobilized on the magnetic glassy carbon electrode (imprinted Fe3O4/PDA-PtNPs/MGCE) for Hb sensing. The imprinted Fe3O4/PDA-PtNPs …
