A biosensor chip integrated interdigital microelectrodes was proposed and applied to monitor the formation process of Salmonella and E. coli biofilms in this paper. The biosensor chip was composed of a glass substrate with interdigital microelectrodes and PDMS layer with micro cavities. The electroc...
