Abstract
A pesticide vapor sensor was developed using an agarose gel-based chip containing a nanopore sensing system. Vaporized omethoate was detected by the absorption into the gel, the complex formation with a DNA aptamer, and its obstruction at the nanopore. This strategy is applicable to other vapors, expanding the versatility of nanopore sensors.
