Abstract

A new set of PVA hydrogels were formed using the boronate ester fluorescent probe PF1 and the novel boronate fluorescent probe PT1 as the covalent crosslinkers. Treatment with aqueous H₂O₂ allowed triggered release of the fluorescent dye accompanied by complete dissolution of the hydrogel.
