Abstract: A chemiresistive sensor is described for the lung cancer biomarker hexanal. A compositeconsisting of molecularly imprinted polymer nanoparticles and multiwalled carbon nanotubes was used in the sensor that istypically operated at a voltage of 4V andis capable of selectively sensing gaseous hexanal at room temperature. It works in the 10 to 200ppm concentration range and has a 10ppm detection limit (at S/N = 3). The sensor signal recovers to a value close to its starting value without the need for heating even after exposure to relatively high levels of hexanal
