Chemical gas sensors based on calixarene-coated discontinuous gold films

We have designed, manufactured and measured performance of novel chemical gas sensors, which are based on conductivity modulation of discontinuous gold films on a dielectric substrate. The sensor elements were functionalized with different calixarenes. Several volatile analytes were exposed and dynamical sensor responses were investigated. Physical principles of the sensor operation are discussed. Our results show applicability of the proposed approach for chemical sensing and recognition.
