Abstract

original image

Sensor strategy bears fruit: A nature-inspired CuI complex was employed to fabricate single-walled carbon nanotube sensors that can selectively detect ethylene gas at concentrations as low as 0.5 ppm. Such nanosensors may be used to monitor ethylene gas emitted from fruits to monitor their ripening.
