Used in bioconjugation and drug delivery systems due to its multi-functional structure, enabling crosslinking with biomolecules or formation of hydrogels. Its norbornene end groups allow for rapid, specific thiol-ene or photoclick reactions under mild conditions, making it ideal for creating biocompatible scaffolds in tissue engineering. Also applied in creating stable protein-polymer conjugates that enhance therapeutic half-life and reduce immunogenicity. Commonly used in 3D bioprinting and in situ gelation applications where fast, controlled network formation is required.
