Dr. Lee has nearly 20 years of research and development experience in the field of biomedical gels at various places (China, US, Singapore, and Korea). In recent years, he has performed a lot of basic research work in the field of protein-based hydrogels and obtained a series of scientific research results. The results have laid a solid foundation for the further industrialization of protein-based hydrogels in the field of bio-ink and 3D bio-printing. In addition, he also has used protein-based hydrogels to construct highly ordered and connected porous three-dimensional cell scaffolds with full protein bases, which has a very prominent application development prospect in the field of three-dimensional cell culture and drug screening.
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.
