GOALI: Addressable Multielectrode Arrays Based on Membrane Templates: Fabrication, Characterization, and Instrumentation

乔治亚州立大学的Cynthia Zoski教授和CH Instruments的何培新博士是由GOALI资助的分析和表面化学项目。该项目是开发微电极阵列作为复杂样品研究的多组分传感器。该阵列的每个元件由一组平行连接的纳米到微型电极组成。每个集群都可以通过多通道恒电位器单独寻址。阵列的开发，包括电极表面的化学修饰和表征，将在大学进行，仪器、电路和软件将与CH Instruments合作开发。阵列表征将在一定程度上通过扫描电化学显微镜的新应用进行。目标应用包括细菌检测和重金属筛选。这项研究的目的是开发一种能够多种应用的仪器，包括用于环境和国土安全监测的化学和生物传感。

Professor Cynthia Zoski of Georgia State University and Dr. Peixin He of CH Instruments are funded through a GOALI grant in the Analytical and Surface Chemistry Program. The project is to develop microelectrode arrays as multicomponent sensors for the study of complex samples. Each element of the array consists of a cluster of parallel-connected nano- to micro-sized electrodes. Each cluster can be individually addressed by a multichannel potentiostat. The development of the arrays, including chemical modification of the electrode surfaces and characterization, will be performed at the University, and the instrumentation, circuitry and software will be developed in collaboration with CH Instruments. Array characterization will be carried out, in part, by the novel application of scanning electrochemical microscopy. Target applications include bacterial detection and heavy metal screening. This research is aimed at developing an instrument that is capable of many applications, including chemical and biological sensing for environmental and homeland security monitoring.
