ABSTRACT
Objective To develop a novel strategy for separation and purification of target protein by magnetic molecularly imprinted nanoparticles . Methods Fe3 O4 nanoparticles were synthesized through a hydrothermal method .A sol-gel technique was adopted to prepare imprinting layers .The adsorption capability of magnetic molecularly imprinted nanoparticles was investigated by kinetic , isothermal , and selective binding experiments .Results The imprinted nanomaterials could reach equilibrium within 30 min . The adsorption capacity was 44 .51 mg/g .The imprinting factor and selectivity coefficient were 3 .50 and 2 .92 ,respectively .The resulting imprinted polymers could selectively separate and enrich bovine hemoglobin from a bovine blood sample . Conclusion The prepared imprinted nanomaterials with good specific adsoprtion ability can provide an effective strategy for separation and purification of target protein .
