We investigated the change in electrical properties of a field-effect transistor (FET) using molybdenum disulfide, MoS₂, as a channel material when it was brought into contact with a solution containing trace molecules. We investigated the function of MoS₂-FET as a sensor. Alcoholic and aqueous solutions containing trace amounts of dopamine molecules were introduced to MoS channel surface via microfluidic channels made of polydimethylsiloxane (PDMS) and its electrical properties were investigated. We detected changes in electrical properties depending on the concentration of dopamine molecules.
