Protein-cross-linked polymeric materials through site-selective bioconjugation

Researchers at the University of California, Berkeley (USA) have now developed a new strategy for the formation of hybrid materials from synthetic polymers and proteins. They have thus been able to fuse the specific biological functions of proteins with the advantageous bulk and processing properties of plastics.
