Abstract/OtherAbstract:
In this study, we report a facile method for the preparation of core-shell magnetic molecularly imprinted polymers (MIPs) for protein recognition. Uniform carboxyl group functionalized Fe(3)O(4) nanoparticles (NPs) were synthesized using a solvothermal method. Magnetic MIPs were synthesized by self-polymerization of dopamine in the presence of template protein on the surface of the Fe(3)O(4) NPs. A thin layer of polydopamine can be coated on Fe(3)O(4) NPs via dopamine self-polymerization and the imprinted polydopamine shells can be controlled by the mass ratio of Fe(3)O(4) NPs and dopamine. More importantly, there is a critical value of polydopamine shell thickness for the maximum rebinding capacity. The as-prepared lysozyme-imprinted Fe(3)O(4)@polydopamine NPs show high binding capacity and acceptable specific recognition behavior towards template proteins. This method provides the possibility for the separation and enrichment of abundant proteins in proteomic analysis.
