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.

We integrated these biologica previously developed device. A fea performed using a vapor phas organophosphorus pesticide, and repre demonstrating long-and-deep current bl presence of the omethoate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
