The utility of visible-light-mediated polymerization in tissue engineering has been limited due to the necessary use of potentially cytotoxic coinitiator and comonomer. Here, we report a visible-light-mediated thiol-ene hydrogelation scheme using eosin-Y as the only photoinitiator. Under visible light exposure
