Methacrylated Gellan-Gum Photoresins: Microbial Identity, Acyl State, Methacrylation, Thermo-Ionic-Photo Networks, Extrusion, Hydration and Qualification

Photocurable gellan-gum systems span gellan gum methacrylate (GGMA), injectable GGMA/PEG-dimethacrylate formulations, ionically or photo-crosslinked cell carriers, and extrusion-printed composites. Pacelli et al. linked functionalisation to solubility, mechanics, swelling and release; Tsaryk et al. compared ionic and photo-crosslinked cell constructs; D'Amora et al. resolved synthesis, printing and post-crosslinking; and Annurakshita et al. added ionic pre-crosslinking and gallol functionality. This review separates parent identity, substitution, thermo-ionic history, photoconversion, process, hydration, network attribution and biological evidence.
