Abstract : Chemical microsensors are fabricated by applying Dithiolene transition metal complexes as thin films to chemiresistor devices using the Langmuir-Blodgett technique. The thin films interact with ambient gases and change electrical conductivity upon exposure to a particular gas or vapor. The film material determines the chemical sensitivity and selectivity. The degree of current change depends on the particular gas or vapor and its concentration. These compounds are different in structure and electrical conductive response to gas or vapors than previous materials used for chemical microsensors. This invention is particularly suited for hydrazine detection.
