a I–V curve of the fabricated device without gas exposure showing complete electrical isolation between upper and lower gold electrodes. b Sensor analysis over one complete cycle of exposure to 40 ppm cadaverine gas and its removal. The sensor signal is compared to the response of a ‘control’ chip, which is our nanogap device without proper functionalization exposed to 40 ppm cadaverine for the entirety of the experiment. G/G0 is the conductance of the sensor normalized to its lowest value, G0 (prior to gas exposure)
