Ultralow Voltage, OTFT‐Based Sensor for Label‐Free DNA Detection. (2nd October 2012) - Lai, S.
Abstract An organic ultralow voltage field effect transistor for DNA hybridization detection is presented. The transduction mechanism is based on a field‐effect modulation due to the electrical charge of the oligonucleotides, so label‐free detection can be performed. The device shows a sub‐nanometer detection limit and unprecedented selectivity with respect to single nucleotide polymorphism.
