Bacterial Concentration Detection with Dielectrophoresis and Capacitive Measurement

Abstract

The concentration of Escherichia coli (E. coli) cells in 1 μl droplet of water was detected by depositing them on an array of electrodes using dielectrophoresis (DEP). Electrowetting was used to effectively concentrate the E. coli in a droplet of water which dried out during the DEP deposition, enabling a simple but powerful system without complicated… (More)
