Injectable hydrogels are important for use in tissue engineering due to their permeability and biocompatibility. Those that have shear thinning properties allow for minimally-invasive surgical procedures and a way to administer bioactive agents, and therapeutic cells by injection. Currently available injectable hydrogels have a single or dual input/stimulus for crosslinking which limits the range of mechanical properties and often utilize potentially toxic ultraviolet radiation that reduces viability of injected cells. To overcome these shortcomings, a tri-stimuli-responsive alginate-based injectable hydrogel was developed based on: 1) supramolecular complex formation between β-cyclodextrin (β-CD) conjugated alginate and thermo-responsive tri-block Pluronic® copolymers, 2) visible light …
