A novel CO2-driven ionic gate, mimicking the function of olfactory sensory neurons of mosquitoes, is successfully developed by functionalizing the walls of the nanochannels using 1-(4-amino-phenyl)-2,2,2-trifluoro-ethanone. This artificial nanochannel can switch between the ON-state and OFF-state in the presence and absence of CO2, with an ultrahigh gating ratio of up to 1250, and has potential applications in CO2-related sensing, gating, and nanofluidic systems
