ALEXANDRIA, Va., Aug. 26 -- Intel, Santa Clara, Calif., has been assigned a patent (8,512,559) developed by Shriram Ramanathan, Portland, Ore., and Chang-Min Park, Portland, Ore., for a "device, method, and system for separation and detection of biomolecules and cells."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "Embodiments of the invention relate to device, method, and system for separation and/or detection of biological cells and biomolecules using micro-channels, magnetic interactions, and magnetic tunnel junctions. The micro-channels can be integrated into a microfluidic device that may be part of an integrated circuit. Magnetic interactions used for the separation are created, in part, by magnetic stripes associated with the micro-channels. Detection of biological cells and biomolecules is effectuated by a magnetic tunnel junction sensor that comprises two ferromagnetic layers separated by a thin insulating layer. The magnetic tunnel junction sensor can be integrated into a silicon based device, such a microfluidic device, an integrated circuit, or a microarray to achieve rapid and specific separation and/or detection of biomolecules and cells."
The patent application was filed on Nov. 18, 2005 (11/281,891). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8512559.PN.&OS=PN/8512559&RS=PN/8512559
