Appl. No.:

17/317184

Inventors:

- PRINCETON NJ, US
Daniel E. GUZMAN - East Brunswick NJ, US

International Classification:

B01L 3/00

Abstract:

Micro-valve system includes two or more superimposed tubes and a pressing device for fluid control in miniaturized capillary connections. The micro-valve system and method of fabrication can be tailored to the requirements of a wide range of applications; composition, sturdiness and thickness of plastic tubes; and capable of been adapted to the resilient of mechanical pressure and the passing and transport of fluid types.

Abstract:

The present invention relates to an immunoaffinity device for capturing, isolating and purifying one or more analytes of interest present at high or low concentration in simple or complex matrices. The device is designed as an integrated modular unit that includes one or more analyte concentrator-microreactor devices anchored into a T-shaped support box, which is built-in or connected to a interchangeable cartridge-cassette of a capillary electrophoresis or liquid chromatography apparatus for the isolation, enrichment, derivatization, separation and characterization of small molecules and polymeric macromolecules, primarily protein and peptide biomarkers. The integrated modular unit is also designed to perform metabolic or bioactivity studies.
