There has been great progress recently in the use of organic and carbon-based materials as the active conductors in electronic sensors for chemical species (analytes). Three principal classes of such materials are conjugated oligomers/polymers, carbon nanotubes, and molecularly imprinted polymers. These materials may be equipped with receptor subunits for analyte binding specificity, and show changed conductances when analytes bind or adsorb. There has been further advancement in the assembly of devices based on these materials into circuit elements that provide output suitable for data processing and networking. Examples of sensors based on these principles, and the mechanisms by which they transduce chemical to electrical information, are reviewed in this chapter.
