Patent number: 7852470Abstract: A portable substance identification system and method are configured to identify at least one detection target faster and with greater accuracy than is possible using prior substance identification systems and/or prior substance identification techniques. An embodiment of the portable substance identification system includes a portable substance identification device containing a Raman spectrometer, and a collection stem that includes a dry collector. One or more reservoirs for a liquid medium and/or a reagent can be formed in a cartridge that is configured to couple with a portable substance identification device. The cartridge has a chamber in which the reagent, liquid medium, and a detection target picked up by the dry collector are mixed. A magnet, positioned at a slant angle, can be used to form at least one pellet of aggregated magnetic particles within a pellet forming area of the chamber. The pellet is formed to maximize its surface area.Type: GrantFiled: December 28, 2007Date of Patent: December 14, 2010Assignee: Morpho Detection, Inc.Inventors: Michael Craig Burrell, Frank Mondello, Tracy Lynn Paxon, William Scott Sutherland, Christopher Montalbano, Gregory Montalbano, Aaron Klein

Publication number: 20100279272Abstract: Methods are described for performing a multiplexed analysis of a level of target analyte in a sample, employing an identifier and a labeling reagent. Either or both of the identifier and the labeling reagent comprises a SERS-active nanoparticle associated with a SERS-active reporter with a uniquely identifiable spectroscopic signature. Interrogation of the identifier and the labeling reagent is conducted by serial coincident detection. Such methods can provide enhanced multiplexed analysis of analytes in a sample, especially with regards to improving the type of identifying reagents that are employed.Type: ApplicationFiled: February 13, 2008Publication date: November 4, 2010Inventors: Michael Craig Burrell, John Yupeng Gui, Frank John Mondello, Andrew David Pris, Tracy Lynn Paxon
