This research program deals with the development and application of laboratory-on-a-chip or capillary electrophoresis microchips to meet various sensing needs. Areas of interest include (1) explosives detection in seawater, (2) toxic metal ion detection on building surfaces, (3) chemical warfare agent simulant monitoring, and (4) biowarfare agent simulant detection. We are enhancing sensitivities by coupling to the microchip various solid phase extraction methodologies (either ex-situ or in-situ). Analytical detection methods applied to the microchip include amperometric, absorbance, fluorescence, chemiluminescence, conductivity, and optical pressure techniques. We are interested in pursuing various pre- and post-column derivatization designs for enabling unique sensing capabilities on chip.
