A Paper‐based Mitochondrial Electrochemical Biosensor for Pesticide Detection

In this article, we detail a paper-based three-electrode electrochemical biosensor using a mitochondria modified Toray carbon paper working electrode. Cyclic voltammetry performed on the paper-based biosensor and similar electrodes in a common laboratory setup (not in an integrated paper-based device) compare favorably. In addition, instant detection of malathion with a detection limit of 20 nM by cyclic voltammetry is demonstrated, showing the device can potentially be used as a portable platform for pesticides detection.
