Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>We present the concept of logic functions based on a single stimuli‐responsive nanopore and analyze its potential for electrochemical transducers and actuators. The responsive molecules at the surface of the polymeric nanopore immersed in an electrolyte solution are sensitive to thermal, chemical, electrical, and optical stimuli, which are the input signals required to externally tune the conductance of the nanopore (the logical output). A single nanostructure can be operated as a resistor or as a diode with a broad range of rectifying properties, allowing for logical information‐processing schemes that are useful pH and temperature sensors, electro‐optical detectors, and electrochemical actuators and transducers. Some of the limitations to be addressed in practical applications are also cited.</p> </abstract>
