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

佐治亚州立大学的辛西娅·佐斯基教授和CH仪器的何培新博士是通过分析和表面化学项目的目标基金资助的。该项目是开发微电极阵列作为研究复杂样品的多组分传感器。该阵列的每个元件由一组平行连接的纳米到微米尺寸的电极组成。每个簇可以由多通道恒电位仪单独寻址。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。阵列表征将部分通过扫描电化学显微镜的新应用来实现。目标应用包括细菌检测和重金属筛选。这项研究旨在开发一种能够应用于许多领域的仪器，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.
