Electrical cell impedance sensing (ECIS) provides an interesting potential towards real time label free diagnostic tools. Its current use to measure cell growth and study the cell cultures requires transmission and fluorescent microscopy to confirm the results. Gold electrodes traditionally used in ECIS hinder the microscopy and hence the use of a new material that allows electrical measurements and improved level of microscopy is essential. PEDOT, a conducting polymer, can bridge the gap between ECIS and microscopy, hence paving the way for new sensor systems and satisfying the traditional biologists who desire confirmation of results through microscopy.
