In situ formation of enzyme-free hydrogels via ferromagnetic microbead-assisted enzymatic cross-linking†
Abstract
In situ formation of horseradish peroxidase (HRP)-free gelatin hydrogels was achieved via ferromagnetic microbead-assisted enzymatic cross-linking. Gelation time and mechanical stiffness of the hydrogels can be tuned in situ, which makes HRP-free gelatin hydrogels suitable for injectable cell delivery.
