Trends in analysis of explosives by microchip electrophoresis and conventional CE.

The continuous upsurge in terrorist activity has generated tremendous demand for innovative tools capable of detecting nitrated organic, inorganic, and peroxide-based explosives. This article directly extends the previous exhaustive review (Electrophoresis 2006, 27, 244-256) and overviews the research activity in the field of microchip and conventional capillary electrophoresis for analysis of a variety of explosive compounds and mixtures in the past two years (middle 2005-middle 2007), with the focus on world-to-chip interfaces and detection techniques.
