Outline of Final Research Achievements

Non-enzymatic glucose sensors without enzymes were developed by modifying the surface of electrodes with glucose-sensitive synthetic molecules.The synthetic molecules are composed of glucose-binding phenylboronic acid moiety and redox-active ferrocene group. Glucose sensors were prepared by immobilizing the compounds on metal electrode. In cyclic voltammetry and differential pulse voltammetry, the modified electrode showed redox waves at approximately 0.3 V, which were sensitive to glucose and fructose at pH 7.0-9.0. The glucose sensors exhibited the electrochemical response to glucose in the concentration range of 1-20 mM, suggesting potential application of the sensors to the determination of blood glucose.
