Pesticide vapor sensing using an aptamer, nanopore, and agarose gel on a chip

Lab Chip. 2017 Jul 11;17(14):2421-2425. doi: 10.1039/c7lc00361g.

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.
