self-healing hydrogels
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Self-healing hydrogels are particularly interesting because of their abilities to repair the structural damages and recover the original functions... self-healing hydrogels with shear-thinning properties can be potentially used as the vehicles for drug/cell delivery or the bioinks for 3D printing by reversible sol-gel transitions.
