DESCRIPTION:

The Ultra-Sensitive Portable Capillary Sensor (U-PAC) is a complete, battery operated, analytical systems packaged in a lightweight, portable carrying case.  The unit is used for highly selective and sensitive detection of biomolecules by means of optical fluorescence using a diode laser for excitation and a photo sensor module for detection.  The sensing surface is contained within interchangeable, disposable glass capillaries.  This allows the user to determine the application of the analysis without making any changes to the instrument itself.  The output signal from the system can be monitored via the on-boards readout, laptop computer or PDA.  The (U-PAC) is a versatile system with a broad range of possible field and laboratory applications.  It can provide parts per trillion analyses with minimal user training.

ADVANTAGES:

The major advantage of the system is a combination of its high sensitivity and its portability.  The U-PAC can be used for field measurements and produces detection limits several orders of magnitude better than that widely accepted enzyme linked immunosorbent assay (ELISA) that must be performed in a laboratory.  Additionally, the systems is easy to sue and does not require extensive training.
