Abstract
Strain-promoted oxidation-controlled cyclo-octyne-1,2-quinone cycloaddition (SPOCQ) is a fast and activatable cross-linking strategy for hydrogel formation. Gelation is induced by oxidation, which is performed both chemically using sodium periodate and enzymatically using mushroom tyrosinase. Due to the fast reaction kinetics, SPOCQ-formed hydrogels can be functionalized in one-pot with an azido-containing moiety using SPAAC cross-linking.
