Janus gas: reversible redox transition of Sarin enables its selective detection by an ethanol modified nanoporous SnO₂ chemiresistor.

Abstract

A reversible janus gas redox transition was discovered in the trace Sarin sensing process using an ethanol-aged nanoporous SnO2 micro-chemiresistor, which was reliable to realize the identification of Sarin from other gases and even its simulant. This sensor also endows a rather low detection threshold of 6 ppb to Sarin.
