Abstract

original image

An efficient and reversible ionic gating that can be activated by pH and light is demonstrated on page 6193 by Lei Jiang, Zhishan Bo, and co-workers, by modifying a malachite green derivative on the interior surface of an ion track-etched conical nanochannel. The switches between the OFF-state and the ON-state are dependent on the surface charge transition caused by the malachite green derivative, making it suitable for confined spaces. Such a dual-driven ionic gating could find applications in electronics, actuators, and biosensors.
