The biotoxin device utilizes micro-scale liquid-phase chromatography and capillary electrophoresis together with laser-induced fluorescence (LIF) detection to provide sensitive analyses at low nanomolar concentration levels.
A two-channel device has been developed and tested which utilizes capillary zone electrophoresis and capillary gel electrophoresis to provide orthogonal analyses of protein mixtures.
| Sandia's µChemLab™/CB device performs fully automated parallel channel analysis for protein biotoxins  Gen2 Biotoxin Detection Box   Chip  Miniature blue diode lasers provide fluorescence excitation light 
Microfluids are manipulated using high voltage control  Fluorescently-tagged proteins are separated "on chip" in fused silica substrates using capillary zone electrophoresis (CZE) and capilary gel electrophoresis (CGE). Data analysis software inentifies and quantitates protein biotoxins. |
