Biological ion channels are able to control ion‐transport processes precisely because of their intriguing properties, such as selectivity, rectification, and gating. Learning from nature, scientists have developed a promising system—solid‐state single nanochannels—to mimic biological ion‐transport properties. These nanochannels have many impressive properties, such as excess surface charge, making them selective; the ability to be produced or modified asymmetrically, endowing them with rectification; and chemical reactivity of the inner surface, imparting them with desired gating properties. Based on these unique characteristics, solid‐state single nanochannels have been explored in various applications, such as sensing. In this context, we summarize recent developments of bioinspired solid‐state single nanochannels with ion‐transport properties that resemble their biological counterparts, including selectivity, rectification, and gating; their applications in sensing are also introduced briefly.
