  • Hydrogels and Hyaluronic Acid and Alpha, Beta-Polyaspartyl-Hydrazide and Their Biomedical and Pharmaceutical Uses
    Publication number: 20080292664
    Abstract: Compositions and products based on the chemical crosslinking of hyaluronic acid with a polyfunctional polymer having a protein-like structure, bearing hydrazido pendent groups along the polymeric chain. The polymer is preferably, alpha-beta-polyaspartylhydrazide, a biocompatible macromolecule. The materials obtained after crosslinking, specifically hydrogels, undergo a reduced chemical and enzymatic degradation, unlike the starting hyaluronic acid, and they can be used to prepare systems for applications in the biomedical and pharmaceutical field.
