Resumen de: WO2026020697A1
The present invention pertains to the technical field of novel biomaterials. Disclosed is use of hyaluronic acid in improving the performance of a polysaccharide-polypeptide composite hydrogel. The present invention, on the basis of the self-assembly characteristics of polypeptides, prepares polysaccharide-polypeptide composite hydrogels with hyaluronic acid (HA) at different concentrations. It has been verified that compared to a single polypeptide hydrogel free of HA, HA reduces the mechanical properties of the composite gels, but can still slow the degradation of the composite hydrogels and improve the stability thereof. HA can also improve the ability of the composite hydrogels to load quercetin and hesperidin, playing a role in slowing the in vitro release of the two, which is conducive to the sustained release of active substances. Moreover, the addition of HA does not affect the secondary structures and micro-nano structures of the composite hydrogels, and can also improve the strength of non-covalent interactions between molecules, improving the stability of the composite hydrogels. The present invention explores the effect of HA on the performance of the composite hydrogels and provides a theoretical basis for the research of hydrophobic drug delivery carriers.
