| 英文摘要 | 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 fe3o4 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 fe3o4 nps. a thin layer of polydopamine can be coated on fe3o4 nps via dopamine self-polymerization and the imprinted polydopamine shells can be controlled by the mass ratio of fe3o4 nps and dopamine. more importantly, there is a critical value of polydopamine shell thickness for the maximum rebinding capacity. the as-prepared lysozyme-imprinted fe3o4@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. |
