Abstract
Provided herein are bioactivated polymer/extracellular matrix (ECM) composites and methods of preparation and use thereof. In particular, heparinized cysteine-polymer/ECM composites, and methods of preparation and use thereof, are provided. In some embodiments, provided herein are compositions comprising a composite of: (a) extracellular matrix (ECM), and (b) a polyester covalently linked to a bioactive agent. In some embodiments, the composite is a homogeneous composite. In some embodiments, the ECM is decellularized ECM. In some embodiments, the ECM is not substantially crosslinked.

A composition comprising a composite of:
- (a) extracellular matrix (ECM), and
- (b) a polyester covalently linked to a bioactive agent.
A composition comprising a composite of:
- (a) extracellular matrix (ECM), and
- (b) a citric acid polyester.
A method of immobilizing a bioactive agent within extracellular matrix (ECM), comprising reacting a first clicking group on the bioactive agent with a complementary clicking group on a polymer, the polymer being in a composite with the ECM, thereby immobilizing the bioactive agent on the polymer.
