General description

Adipic acid dihydrazide is commonly used as a functional group to allow for HA cross-linking to polymers containing aldehyde groups or that are aldehyde-functionalized, like HA-aldehyde or PEG-aldehyde. These biomaterials are attractive for their tunable properties and low cytotoxicity.
Degree of functionalization (50-80%)


Hyaluronic acid (HA) is a ubiquitous extracellular matrix component, which makes it attractive for use in medical applications for it′s biocompatibility and low immunogenicity. HA-based polymers are used to make hydrogels for a wide variety of applications from tissue engineering and regeneration to drug delivery and bioinks for 3D bioprinting. To make hydrogels, HA has to be derivatized with groups that can cross-link to to other functionalized polymers.

Synthetic hydrogel scaffolds that can be used as culture systems that mimic the natural stem cell niche are of increased importance for stem cell biology and regenerative medicine. These artificial niches can be utilized to control the stem cell fate


Rational Design of ECMs Toward Cancer Immunotherapy

Engineered ECMs enhance immune therapy in cancer treatment by supporting cells and tissues and modulating immune response. They improve immune cell maturation, expansion, and regulation through biomaterial manipulation, acting as frameworks or carriers for enhanced tumor immunotherapy.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
