  • Photo-crosslinked gellan gum-based hydrogels: preparation methods and uses thereof
    Patent number: 9012415
    Abstract: This invention refers to photo-crosslinked hydrogel materials based in gellan gum suitable for tissue engineering and regenerative medicine applications or as drug delivery systems. Formulations of gellan gum with different degrees of acylation serve as precursor material for insertion of a polymerizable moiety. The materials are capable of free radical polymerization with a photo-initiator at mild temperatures and exposure to ultraviolet light, enabling control of reticulation and withstanding the encapsulation of human and animal cells and/or drugs, and any combination thereof. The physicochemical and biological properties can be adjusted by combining different formulations of gellan gum and reaction conditions.
    Type: Grant
