Solution-gated ITO-TFTs composed from a single ITO film can be easily fabricated by etching a part of a 100-nm conductive ITO film to thin it down to about 20 nm to exhibit semiconductor properties, which shows a steep subthreshold slope close to the thermal limit. This study attempted highly sensitive biosensing utilizing the steep subthreshold slope by measuring biomolecules modelled after DNA molecules.
