摘要: A chemically-gated single-electron transistor (60) having a predetermined current-voltage characteristic and adapted for use as chemical or biological sensor that is operable at room temperature. The comprises substrate (SuB) formed of first insulating material, source (S) drain (D) electrodes disposed on the substrate, metal nanoparticle (L) between has spatial dimension magnitude approximately 12 nm less. An analyte-specific binding agent surface nanoparticle. event occurring target analyte causes detectable change in characteristic.
