Bioinspired fluorescent dihydroxyindoles oligomers

Abstract In this paper we report the desgin and synthesis of dihydroxyindoles oligomers based reversible fluorescence sensor. We find dihydroxyindoles-2-carboxylic acid derived oligmer (P-DHICA) has the highest selectivity and sensitivity for Cu 2+ detection. This work provide a highly efficient, environmentally friendly biosensor for potential use in medical testing.
