Abstract: A molecular imprinted polymer was prepared using bovine serum albumin as the template molecule, iron oxide magnetic nanoparticles as the carriers and dopamine as the functional monomer. The prepared magnetic molecularly imprinted polymer nanoparticles (MNP-MIPs) were applied to adsorb protein and the protein adsorption capacity was measured. The results indicated that the adsorption capacity towards protein exhibited an increase up to the saturation level with prolonged adsorption time. Similarly, the adsorption capacity also revealed an increase trend as the template concentration rose and other conditions were kept unchanged. Moreover, bovine serum albumin could be specifically adsorbed by MNP-MIPs.
