Abstract

The surface of a gold (Au) disk electrode was modified with layer-by-layer (LBL) films consisting of phenylboronic acid polymer and carboxymethylcellose to fabricate a voltammetric sugar sensor. The modified Au electrode exhibited a voltammetric response to D-glucose and D-frucose in the presence of Fe(CN) 63- ion in the sample solution at neutral pH. The peak current of the cyclic voltammograms decreased, depending on the concentration of sugars. The dynamic range in the calibration graph is 0.1∼300 mM for D-glucose and D-fructose.
