Highly sensitive VOC detectors using insect olfactory ...

Although highly sensitive VOC sensors based on ORs have been previously proposed for detecting VOCs dissolved in solutions (7, 25), only a few studies have shown successful VOC detection directly from the gas phase (4, 8, 10). Therefore, the low solubility of VOCs limits the development of OR-based sensors. Our system facilitates the introduction of VOCs into droplets through continuous gas ...
