A group of researchers from Japan’s Osaka University have developed a new bioprinting ink using a method based on hydrogelation mediated by horseradish peroxidase, an enzyme that can create cross-links between phenyl groups of an added polymer in the presence of the oxidant hydrogen peroxide. This bioprinting ink will be better substitute of Sodium Alginate as it will allow 3D Printing of more variety of scaffolds.
