  • Method and sensor for detecting volatile enantiomeric substances in gases
    Patent number: 6033630
    Abstract: A method and sensor for distinguishing between different optical isomers (enantiomers), which sensor comprises a pair of spaced-apart contacts and a semi-conductive polymer material spanning the gap between the contacts, which polymer material includes chiral sites. The chiral sites in the polymer material are preferably formed by incorporating an optically active counterion into the polymer material, for example by growing the polymer in the presence of such a counterion, e.g. camphor sulphonic acid.
