Conteúdo: |
Pure and composite nanostructured films of conducting polymers were used as individual sensing units constituiting an electronic tongue. The use of extremely thin films for signal transduction via impedance spectrosocpy measurements in the frequency range 10-1 MHz allows the detection of trace amounts of tastants and inorganic contaminants in liquid systems. In addition, the sensor could detect the suppression of sourness by sweetness displaying similarities with the biological system. Brands of several commercial beverages could be easily distinguished without complex analysis, including the discrimination of wasters, tastants and wines. |
