Abstract

An organic ultra-low 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 sub-nanometrical detection limit and unprecedented selectivity with respect to single nucleotide polymorphism.
