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.
