Functionalized biopolymers

Functionalized Glycosaminoglycan derivatives (GAG derivatives)

HTL offers the tailor-made development of functionalized derivatives of Glycosaminoglycans, such as modified Hyaluronic Acid and Heparosan. Developing new functionalities by chemical modification allows the optimization of existing uses of these biopolymers, but also opens opportunities for new medical applications.
