A boronic acid-appended fluorescent receptor was incorporated into self-assembled nanofibers containing a hydrophobic FRET-paired dye to develop a gel-based fluorocolorimetric sensor for polyols. We demonstrated that the gel-based sensor is capable of detecting polyols such as catechol and dopamine not only under semi-wet conditions, but also under dry conditions using a paper platform.
