Specialized microelectrode probes fabricated in a soft polymer film now make it possible to use scanning electrochemical microscopy (SECM) to image the reactivity of large, corrugated, tilted, and dry surfaces. In their article Fernando Cortés-Salazar, Dmitry Momotenko, and Hubert H. Girault discuss the features and applications of the technique. The image shows a fountain pen probe for dry surface imaging and an array of microelectrodes for imaging large surfaces.
