Development of {micro}Chemlab{sup TM}/CG for Detection of Biotoxins

Conference ·
OSTI ID:772349
The authors have developed a research prototype device for low level detection of SEB, ricin, botulinum toxin and ovalbumin in liquid samples. This hand-held, low power device analyzes samples by capillary zone electrophoresis (CZE) and capillary gel electrophoresis (CGE) in a parallel microchannel format, and provides sensitive detection of fluorescently-tagged analytes using miniature 392 nm diode laser-induced fluorescence. They have successfully demonstrated simultaneous parallel channel separations, fully automated high voltage control of fluidics and automated data analysis with toxin identification and semi-quantitation in the presence of aerosol backgrounds in a stand-alone self-contained unit. Tests of the fully integrated device indicate high sensitivity detection (as low as 5 nM) and cycle times of 5-10 minutes.
