The combination of high sensitivity and portability Versatile system with a broad range of possible field and laboratory applications.


The Ultra-Sensitive Portable Capillary Sensor (U-PAC) is a complete, battery-operated, analytical system packaged in a lightweight, portable carrying case. It is a rapid, sensitive, and easy to operate portable immunochemistry testing platform that can be utilized by minimally trained personnel where it is needed most, at the point of collection, point of care and point of crisis (POC). The U-PAC is a culmination of a careful integration of optics, fluidics, electronics, and software into one compact system for laboratory and field assays. 

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 onboards readout, laptop computer or PDA. 


The combination of high sensitivity and portability 
Can be used for field measurements and produces detection limits several orders of magnitude better than that widely accepted enzyme linked im-munosorbent assay (ELISA) that must be performed in a laboratory. 
Versatile system with a broad range of possible field and laboratory applications. It can provide parts per trillion analyses with minimal user training.
