Kenneth S. Suslick Ponder, Jennifer B. 2015-09-25T22:13:38Z 2015-09-25T22:13:38Z 10000-01-01 2006 2006 We have developed and patented a unique chemical detection technology in which colorimetric changes in an array of dyes constitute a signal much like that generated by the mammalian olfaction system; each dye is a cross-responsive sensor. This technology uses a disposable printed array of chemically responsive dyes as the primary sensor elements. The dyes undergo reversible reactions that result in well defined color changes due to stronger chemical interactions: ligation to metal ions, Lewis or Bronsted acid-base interactions, hydrogen bonding, etc. Striking visual identification of a wide range of VOCs are easily made at part per billion (ppb) levels with extremely low error rates for Toxic Industrial Chemicals (TICs) at both their IDLH (Immediately Dangerous to Life or Health) and the much more demanding PEL (workday permissible exposure limits). Complex mixtures are easily identified, such as coffees and perfumes, making this technology ideal for quality control applications. This technology is also used for the detection and identification of pathogenic bacterium based on volatile metabolites emitted during growth. Made available in DSpace on 2015-09-25T22:13:38Z (GMT).
