A cytocompatible inkjet bioprinting approach that enables the use of a variety of bioinks to produce hydrogels with a wide range of characteristics is developed. Stabilization of bioinks is caused by horseradish peroxidase (HRP)-catalyzed cross-linking consuming hydrogen peroxide (H2 O2 ). 3D cell-laden hydrogels are fabricated by the sequential dropping of a bioink containing polymer(s) cross-...
