A Disposable, Papertronic Three-Electrode Potentiostat for Monitoring Bacterial Electrochemical Activity.

ABSTRACT: Bacterial electrochemical activities can promote sustainable energy and environmental engineering applications. Characterizing their ability is critical for effectively adopting these technologies. Conventional studies of the electroactive bacteria are limited to insensitive, time-consuming, and labor-intensive two-electrode microbial fuel cell (MFC) techniques. Even the latest miniaturized MFC array is limited by irreproducibility and uncontrollability. In this work, we created a 4-well electrochemical sensing array with an integrated, custom-made three-electrode potentiostat to provide a controllable analytic capability without unwanted perturbations. A simple potentiostat circuit used two operational amplifiers and one resistor, allowing chronoamperometric and staircase voltammetric ana
