Patent number: 9851307Abstract: Embodiments described herein related to devices and methods for the collection and/or determination of analytes, such as illicit substances including military explosives, explosives, and precursors thereof. In some cases, the device may be a disposable device that incorporates highly efficient sample collection in combination with microfluidic-based chemical analysis resulting in the rapid detection and identification of unknown materials. In some cases, multiple colorimetric detection chemistries may be employed, and the resulting “barcode” of color changes can be used to positively identify the presence and/or identity of the analyte.Type: GrantFiled: December 18, 2013Date of Patent: December 26, 2017Assignee: FLIR Detection, Inc.Inventors: Robert Deans, Peter G. Loges, William McDaniel, Kateri E. Paul, Lawrence F. Hancock, Matthew Joseph Szabo

Patent number: 9005524Abstract: The present invention provides a series of systems, devices, and methods relating to the determination of explosives, such as peroxides or peroxide precursors, and other species. Embodiments of the invention may allow a sample suspected of containing an explosive (e.g., a peroxide) or other species to interact with a reactant, wherein the sample may react and cause light emission from the reactant. Advantages of the present invention may include the simplification of devices for determination of peroxide-based explosives, wherein the devices are portable and, in some cases, disposable. Other advantages may include relative ease of fabrication and operation.Type: GrantFiled: July 9, 2010Date of Patent: April 14, 2015Assignee: Nomadics, Inc.Inventors: Robert Deans, Aimee Rose, Kevin M. Bardon, Lawrence F. Hancock, Timothy M. Swager

Patent number: 7462325Abstract: This invention involves a series of articles, dispersions, compositions, methods, and kits. Several aspects of the invention involve dispersed particles made from polymers having a delocalized ?-orbital backbone structure, as well as methods for making and using such particles. The delocalized ?-orbital backbone allows the polymer to have a high degree of luminosity, useful in many embodiments of the invention. The polymers of this invention can also have bulky substituents to prevent intermolecular ?-? interactions that can decrease luminosity. The polymer may also have charged side chains immobilized relative to the backbone, which can allow the polymer to be made into stably suspended micro- or nanoparticles dispersed in solution, sometimes with very narrow size distributions. In some embodiments, depending on the conditions used to synthesize and prepare the particles, the particles each consist of a single polymer molecule.Type: GrantFiled: November 30, 2001Date of Patent: December 9, 2008Assignee: Nomadics, Inc.Inventors: Lawrence F. Hancock, Robert Deans, Wei Chen

Publication number: 20040121337Abstract: The present invention involves a series of articles, compositions, methods, and kits. Some aspects of the invention include articles such as particles, sols, blends, dispersions, films, or microarrays that comprise luminescent polymers, as well as methods for making and using such articles. In some cases, the luminescent polymer may be characterized in part by having a delocalized &pgr;-orbital structure, which can allow the polymer to have a high degree of luminosity. The polymers of this invention may also have, in some embodiments, bulky substituents to prevent intermolecular &pgr;-&pgr; interactions that can decrease luminosity. Some articles may include more than one luminescent polymer, for example, a first polymer that absorbs energy and directs the energy to a second polymer that releases the energy.Type: ApplicationFiled: December 19, 2002Publication date: June 24, 2004Applicant: Nomadics, Inc.Inventors: Robert Deans, Lawrence F.

Patent number: 6172180Abstract: The present invention relates to a block copolymer containing 1-50 first polymer segments and 1-50 second polymer segments. Each first polymer segment has an average mole fraction of monomers possessing a branch point of 0.0001 to 1, whereas each second polymer segment has an average mole fraction of monomers possessing a branch point of 0 to 0.5. The average molecular weights range from 5-2,000 kDa for the first polymer segments, which constitute 5-95% by weight of the block copolymer. The average molecular weights also range from 5-2,000 kDa for the second polymer segments, which constitute 5-95% by weight of the block copolymer. The ratio of the average mole fraction of monomers possessing a branch point of the second polymer segments to that of the first polymer segments is 0 to 0.5. An example of such a copolymer has ethylene oxide or ethylene oxide/propylene oxide as the first polymer segment and polysulfone as the second polymer segment. This block copolymer can further be blended with a bulk polymer.Type: GrantFiled: August 25, 1998Date of Patent: January 9, 2001Assignee: Circe Biomedical, Inc.Inventors: Lawrence F. Hancock, Stephen M. Fagan, Claudy J.-P. Mullon
