Abstract

A highly efficient multi-stimuli-response ionic gate that can be activated separately or cooperatively by pH and UV light has been demonstrated by modifying the environmental stimuli-responsive molecule 8-hydroxypyrene-1,3,6-trisulfonate into a track-etched single conical nanochannel. Such a multi-response ionic gate can find applications in areas such as electronics, actuators, and biosensors.

Keywords: functionalized; gates; multi-response; nanochannels.
