Towards a FAST-CARS anthrax detector: CARS generation in a DPA surrogate molecule Academic Article uri icon


  • Coherent anti-Stokes Raman spectroscopy (CARS) has been investigated as a detection method for the identification of dipicolinic acid (DPA), a marker molecule for bacterial spores of anthrax. The laser dye molecule DCM was used as a surrogate molecule for DPA. In preliminary experiments, a molecular sensitivity was achieved in DCM that is projected to be sufficient to detect the DPA in bacterial spore clumps as small as 5.5 m in diameter, small enough to be of interest in practical detection scenarios. 2003 Taylor & Francis Group, LLC.
