Our team consists of researchers with various backgrounds (chemistry, materials science, biology, and engineering). Our team focuses on the development of protein-based hydrogels for bioapplications including tissue engineering, drug screening, and 3D bioprinting. Protein-based materials exhibit excellent biocompatibility and biological activities. However, their poor mechanical properties limit their wide ranges of bioapplications. Here, we have functionalized protein materials via methacryloylation so that they can be solidified upon exposure to light. Photocrosslinking imparts the spatiotemporal control over biofabrication as well as tailorable mechanical properties. Photocuring is conducted under a mild condition in the presence of a photoinitiator, relatively leading to good biocompatibility. Photocurable protein-based hydrogels have been used to fabricate highly ordered 3D scaffolds/tissue analogues for 3D culture and drug screening applications. Besides, they have been used to print various tissue constructs. Photocurable protein-based hydrogels could become versatile materials for various bioapplications.
