Engineering bioorthogonal protein–polymer hybrid hydrogel as a functional protein immobilization platform

Abstract

We demonstrate the synthesis of protein–polymer hybrid hydrogel that can be used as a platform for immobilizing functional proteins. Orthogonal chemistry was employed for cross-linking the hybrid network and conjugating proteins to the gel backbone, allowing for the convenient, one-pot formation of a functionalized hydrogel. The resulting hydrogel had tunable mechanical properties, was stable in solution, and biocompatible.
