| An aerosolized form of botulinum toxin deliberately released into a public building is a possible bioterroristism problem. The need for an accurate detection system of biological neurotoxins in indoor environments is urgently needed. Differential Mobility Spectroscopy (DMS), has shown the capability for the detection and separation of pyrolyzed BoNT samples. Differential Mobility Spectroscopy is an ion mobility detector that has the advantage of operating at atmospheric pressure and capability of simultaneous detection of multiple compounds in a time scale of seconds. . In the Differential Mobility Spectrometer ions are detected based on the differential mobility in an RF electric field and ion separation is dependent on the charge, size and mass in a changing electric field. The DMS has shown the promise as a detector for biological toxins like BoNT complex with the application of detection in environmental systems. The research was supported by a contract from Charles Draper Laboratory and a contract from CDC. |
