Colorimetric identification of carbohydrates by a pH Indicator/pH change inducer ensemble

Abstract

The sweet-test thing! Carbohydrate discrimination is highly challenging as a result of the similarity in their functional groups. A series of pH sensor/pH change inducer ensembles has been developed as an artificial “tongue” for the identification of carbohydrates. The optimized sensor array with six probe pairs demonstrated full discrimination of 23 carbohydrates.
