Abstract: A sampling system that includes a traverse, a sample aspiration module body, and a mechanical system. The sample aspiration module body is configured to travel along the traverse. The mechanical system is configured to move the traverse from a first position to a second position, wherein both the first position and the second position lie in the same plane.

Abstract: Techniques for the sensitive detection of analytes which combine the benefits of solution/suspension phase assay formats and the simplicity of solid phase/lateral flow assays are described. The assays can be performed in the solution/suspension phase using magnetic microspheres as a solid support. Subsequently a magnetic separation can be performed to separate the bound analyte from the remainder of the solution. After a wash step, the fluorescence signal can be directly read from the magnetic particle surface. Portable biodetection systems which employ fluorescent polymer superquenching and methods for detecting bioagents therewith are also described.

Abstract: High throughput electrophoresis having a plurality of samples migrating through a highly resistive separatory media under an electric field. Multiple electrophoresis runs are conducted using a single separatory media. Automated methods of data analysis yields quantitative and qualitative data using optical densitometer or other detection systems. Controlled operating temperatures and small geometry reduces dispersion inaccuracy in banded data.
