Hyaluronic acid Methacryloyl (HAMA) is a methacrylated form of hyaluronic acid that exhibits biocompatibility. It functions as a 3D printing hydrogel ink, characterized by rapid photosensitivity, quick gelation speed, and stable hydrogel properties. Upon UV exposure, it can rapidly initiate gelation with lithium phenyl-2,4,6-trimethylbenzoylphosphinate (LAP). Additionally, when combined with tissue-specific extracellular matrix (ECM) materials, such as pancreatic extracellular matrix (pECM), Hyaluronic acid Methacryloyl serves as a crucial source material for organoid culture.
