Organic field-effect transistors (OFETs) currently utilize organic semiconductor materials with low electron mobilities and organic gate oxide materials with low dielectric constants. Compared to inorganic FETs, OFETs have slow operating speeds and high operating voltages. In this paper we discuss blending the conductive polymer polyethylene dioxythiophene (PEDOT) with deoxyribonucleic acid (DNA), with minimal optimization to produce a new bio-conductive polymer complex potentially suitable for OFETs. The conductivity of this new bio-conductive polymer complex is tunable, ranging from 10-10 S/cm to 10-3 S/cm at room temperature.
