Patent number: 10545094Abstract: A system and method for the detection of one or more analytes in a collected sample employs capillary action in a sample card containing a sample substrate, at least one test capsule and an absorbent pad. The absorbent pad absorbs the contents of the test capsule and delivers the same to the sample substrate, with the contents of the test capsule chemically reacting with at least one detection reagent to establish an optical indicator for the analyte(s). The sample card can be automatically tested within a reader device, which records and processes an optical signal produced by the chemical reaction and outputs a test result. The collected sample can then be further analyzed using a second device. Additionally, an adhesive component can be provided so that a sample can be collected thereon. Furthermore, the at least one detection reagent can include a surfactant.Type: GrantFiled: November 3, 2017Date of Patent: January 28, 2020Assignee: RedXDefense, LLC.Inventors: Arman Ghodousi, Sarah Josepha Toal, Gregory Scott Ericksen, Daniel Douglas Montgomery, Thomas Emory McVeigh, Jacek Kotowicz, Sean Conte

Patent number: 9435744Abstract: An analyte detection system and method for the detection of one or more analytes in a sample, the analytes selected from the group consisting of explosives, narcotics, gunshot residue, organophosphate reagents, and toxic industrial chemicals, based on a capillary action in a sample card. The sample card includes a housing with at least one cavity made of flexible material, a sample substrate for collecting the sample with a portion of the substrate exposed from outside the housing, at least one test capsule in the cavity and an absorbent pad. The test capsule(s), the sample substrate, and the absorbent pad comprise at least one or more reagents. The test capsule(s) is ruptured with a rupture mechanism upon inserting the sample card into a reader device. The absorbent pad absorbs a liquid from the test capsule and delivers the same to the sample substrate.Type: GrantFiled: April 3, 2013Date of Patent: September 6, 2016Assignee: RedXDefense, LLCInventors: Arman Ghodousi, Sarah Josepha Toal, Gregory Scott Ericksen, Daniel Douglas Montgomery, Thomas Emory McVeigh, Jacek Kotowicz

Publication number: 20150079693Abstract: A product and method for the detection of one or more analytes in a collected sample employs capillary action in a sample card containing a sample substrate, at least one test capsule and an absorbent pad. The absorbent pad absorbs the contents of the test capsule and delivers the same to the sample substrate, with the contents of the test capsule chemically reacting with at least one detection reagent to establish an optical indicator for the analyte(s). The sample card can be automatically tested within a reader device which supplies one or more light sources, records and processes an optical signal produced by the chemical reaction, and outputs a test result.Type: ApplicationFiled: April 3, 2013Publication date: March 19, 2015Applicant: REDXDEFENSE, LLCInventors: Arman Ghodousi, Sarah Josepha Toal, Gregory Scott Ericksen, Daniel Douglas Montgomery, Thomas Emory McVeigh, Jacek Kotowicz

Publication number: 20090246881Abstract: A system and method for detecting trace explosives is provided that utilizes a lumnescent reagent, such as blue-fluorescent biphenyl compound, to simultaneously detect multiple nitrogen-based explosives on a sample substrate. The test reagent is mixed with a solvent to improve mixing and maximize the dissolution of the reagent and any trace explosives present on the substrate. A thin film of reagent is applied to the substrate either before or after the substrate contacts a sample area to be tested. Heated air is then applied to the substrate to improve the sample reading. A light source is utilized to illuminate the reagent and expose any quenched portions of the substrate that indicate the presence of an explosive. Quenched portions may be detected visually, or utilizing an analyzing apparatus, such as a fluorimeter or camera. A computer may also be utilized to interpret and record test results.Type: ApplicationFiled: September 21, 2007Publication date: October 1, 2009Applicant: REDXDEFENSE, LLCInventors: Sarah Josepha Toal, Jennifer Marie Sievering
