The electrode was obtained by entrapping the silver-filled nanotubes into a carbon paste and displays a Nernstian response with a slope of 59.8 ± 0.3mV decade−1, a very wide linear range (from 21.0nM to 0.1M of cyanide), a lower detection limit of 13.0nM, and a response time of <2min. The operational lifetime is up to 3months without significant deviation in normal function.
