The ability of boronic acids to reversibly bind diols, such as sugars, has been widely studied in recent years. In solution, through the incorporation of additional fluorophores, this boronic acid-sugar interaction can be monitored by changes in fluorescence. Ultimately, a practical realization of this technology requires a transition from solution-based methodologies. Herein we present the first example of 3D printed sugar-sensing hydrogels, achieved through the incorporation of a boronic acid-fluorophore pair in a gelatin methacrylamide-based matrix. Through optimization of monomeric cocktails, it was possible to use extrusion printing to generate structured porous hydrogels which show a measurable and reproducible linear fluorescence response to glucose and fructose up to 100 mM.
