MICROELECTRODES, MICROELECTRODE FORMATION, AND METHODS OF UTILIZING MICROELCTRODES FOR CHARACTERIZING PROPERTIES OF LOCALIZED ENVIRONMENTS AND SUBSTRATES

摘要

Microelectrodes, microelectrode formation, and methods of utilizing microelectrodes for characterizing properties of localized environments and substrates are provided. A microelectrode can include a tungsten wire comprising a shaft and a conical tip. The conical tip can include an electroactive area. Further, the microelectrode can include an electroactive coating layer covering one or more surface of the tungsten wire. The tungsten wire surfaces can include a surface of the conical tip. An insulating layer can at least partially cover the shaft.
