石墨烯传感器的研究进展

Research Progress in Graphene-based Sensors

论述了石墨烯电化学和生物传感器的研究进展,包括石墨烯的直接电化学基础、石墨烯对生物小分子(Hydrogen peroxide,NADH,dopamine,etc.)的电催化活性、石墨烯酶传感器、基于石墨烯薄膜和石墨烯纳米带的实用气体传感器(可检测O2、CO和NO2)、石墨烯DNA传感器和石墨烯医药传感器(可用于检测扑热息痛)。

Recent advances in graphene-based electrochemical sensors and biosensors are reviewed. In particu- lar, graphene for direct electrochemistry of enzyme, its electrocatalytic activity toward small biomolecules （hydrogen peroxide,NADH, dopamine, etc. ）, and graphene based enzyme biosensors are summarized in more detail. Perfor- mances of the practical sensors composed of graphene films and ribbons for O2, CO, and NO2 are discussed. Gra- phene-based DNA sensing is discussed. And a novel electrochemical sensor that was fabricated with graphene-modified glassy carbon electrodes（GCEs） is described. It can be used for ultrasensitive determination of paracetamol in pharma- ceutical products.
