Magnetically steerable Fe3O4@Ni2+-NTA-polystyrene nanoparticles for the immobilization and separation of his6-protein

[Display omitted] •Ni2+-NTA-PS NPs encapsulated with magnetic Fe3O4 NPs were synthesized.•The morphology, size and encapsulation were confirmed using SEM, TEM and DLS.•The application of our system was proved by magnetic separation of his6-tag protein. We developed Ni2+-nitrilotriacetic acid (NTA) f...
