16 Plastic Transistors Developing low-voltage organic thin-film transistors with operating voltages below 3V for portable, battery-operated applications Invention disclosure undergoing an internal review at Strathclyde 2 PhD students involved in the transistor development – comprehensive transistor optimization process p-channel transistor parameters obtained to date: p ~ 0.2cm 2 /V · s, V T ~ 1V, S ~ 50mV/decade, I off ~ A, I on /I off ~ 10 6

17 impedance spectroscopy of biological cells provides tool for monitoring cell growth and characteristics using microelectrodes and a larger reference electrode conducting polymers (PEDOT) electrodes instead of metal electrodes PEDOT benefit from the material characteristic of transparency, low cost, biocompatibility, and lower interfacial impedance enhances sensitivity Reference electrode Weakened electrical fields Cell on surface Measuring electrode Regular electrical field Insulation layer Conducting Polymers Applied To Cell Impedance Sensing

18 devices with Au electrodes and PEDOT electrodes in order to compare them devices have three wells Devices and Setup Au electrode device PEDOT electrode Device Electronics and connector for device

19 Results Gold and PEDOT comparison Gold electrodes show very large impedance at lower frequencies compared to the PEDOT electrodes Impedance of the gold electrode reduces the sensitivity of cell impedance measurement and increases influence of noise. Cell growth experiment on PEDOT cells growing on the surface at three different frequencies over 3 days changes at lower frequencies is most prominent. As cells spread and divide they will gradually cover more of the measuring electrode resulting in an increase in the impedance.
