要約(日本語): In recent years, chemical sensing technology has advanced and many sensing films with high sensitivity and selectivity have been reported. However, preparation of multiple sensing films with partially overlapping selectivities is laborious for large chemical information systems. Atomic gold decorated polyaniline conducting polymers are novel sensing materials whose catalytic activity has been controlled by modifying the size of atomic gold clusters. In this research, such functionalized materials have been prepared on planar glass substrates. Electrochemical responses were studied by combining the sensing film with ionic liquid electrolyte. This paper reports further sensor characterization and gas measurements towards target compounds.
