Fabrication of Polymer–Protein Hybrids

Rapid developments in organic chemistry and polymer chemistry promote the synthesis of polymer–protein hybrids with different structures and biofunctionalities. In this feature article, recent progress achieved in the synthesis of polymer–protein conjugates, protein–nanoparticle core–shell structures, and polymer–protein nanogels/hydrogels is briefly reviewed. The polymer–protein conjugates can be synthesized by the “grafting‐to” or the “grafting‐from” approach. In this article, different coupling reactions and polymerization methods used in the synthesis of bioconjugates are reviewed. Protein molecules can be immobilized on the surfaces of nanoparticles by covalent or noncovalent linkages. The specific interactions and chemical reactions employed in the synthesis of core–shell structures are discussed. Finally, a general introduction to the synthesis of environmentally responsive polymer–protein nanogels/hydrogels by chemical cross‐linking reactions or molecular recognition is provided.
