A03 | Thermo-gelling poly(2-oxazolin) based hydrogels with temporal mechanical control

This project aims at developing a synthetic, cell-compatible and modular bioink-platform. Diblock copolymers based on poly(2-oxazoline)s will be deployed exhibiting suitable thermo- and shearresponsive behavior. This novel bioink platform will be modified by a dual-crosslinking mechanism to (i) guarantee mechanical stability after printing and (ii) to modulate the stiffness of the ink during cell-culture experiments.
