Detecting Bacillus Spores by Raman and Surface-Enhanced Raman (SERS) Spectroscopy

June 02, 2005

Raman spectroscopy has been employed to detect Bacillus cereus spores, an anthrax surrogate, collected from a letter as it passed through a mail sorting system. Raman spectroscopy also has the ability to identify many common substances used as hoaxes. A three-step method also is described for the detection of dipicolinic acid extracted from surface spores by SERS.
