Abstract

Small Molecule Metabolite Reporters (SMMRs) for use as in vivo glucose biosensors, sensor compositions, and methods of use, are described. The SMMRs include boronic acid-containing xanthene, coumarin, carbostyril and phenalene-based small molecules which are used for monitoring glucose in vivo, advantageously on the skin.
