DEVICE AND METHOD FOR GROWING A BIOFILM AND MEASURING AN ELECTRICAL PROPERTY THEREOF

摘要

The invention relates generally to a device and a method for monitoring the growth of a biofilm and measuring a property of the biofilm, and in particular, to an integrated device wherein the growth and measurement of the conduction of the biofilm are performed in the same integrated device. The integrated device comprises a flow cell biofilm growth chamber entirely housed within an electrochemical impedance spectroscopy (EIS) chamber. The flow cell biofilm growth chamber comprises a working-electrode-supported substrate and the EIS chamber comprises a counter-electrode-supported substrate, wherein the two substrates are adapted for electrical connection to an external impedance measurement apparatus.
