Patent number: 9810657Abstract: The invention provides electrochemical-based modules useful for the determination of an analyte in a bodily fluid sample. The modules of the invention provide opposed electrodes, but the contact areas for making electrical contact between the electrodes and the analyte measurement device are coplanar.Type: GrantFiled: September 7, 2012Date of Patent: November 7, 2017Assignee: Cilag GmbH InternationalInventors: Steven John Setford, Scott J. Sloss

Patent number: 9541520Abstract: An analytical test strip has mutually-insulated first and second electrodes arranged to define a sample-receiving chamber. Electrically-insulating layers are disposed over respective electrodes. First and second electrical contact pads are electrically connected to the first electrode, and a third pad to the second electrode. A first side of the test strip has a first electrically-insulating layer and the third pad, and a second side has the second electrically-insulating layer and the first and second pads. The third pad extends longitudinally from the sample-receiving chamber farther than does the first electrically-insulating layer. Methods for determining an analyte in a bodily-fluid sample and analytical test systems for use in the determination of an analyte in a bodily-fluid sample are also described.Type: GrantFiled: July 29, 2015Date of Patent: January 10, 2017Assignee: Cilag GmbH InternationalInventors: James T. Moffat, Lawrence Ritchie, Steven John Setford, John Scott, Graeme J. Webster

CO-FACIAL ANALYTICAL TEST STRIP WITH STACKED UNIDIRECTIONAL CONTACT PADS AND INERT CARRIER SUBSTRATE
Publication number: 20130228475Abstract: An analytical test strip with inert carrier substrate for use with a test meter includes an analytical test strip module and an electrochemically and electrically inert carrier substrate. The analytical test strip module has a first electrode portion, a second electrode portion in an opposing relationship to the first electrode portion, and first and second electrical contact pads configured in a stacked unidirectional configuration. The electrochemically and electrically inert carrier substrate has an upper surface and an outer edge. Moreover, the analytical test strip module is attached to the upper surface of the electrochemically and electrically inert carrier substrate such that the first and second electrical contact pads extend beyond the outer edge of the electrochemically and electrically inert carrier substrate and such that the electrochemically and electrically inert carrier substrate extends beyond the analytical test strip module.Type: ApplicationFiled: August 14, 2012Publication date: September 5, 2013Inventors: Steven John Setford, Scott John Sloss, Lawrence Julian Ritchie -
Publication number: 20090068673Abstract: This invention is based upon the application of compatible solutes to immobilized biological materials or to immobilize in order to improve the technical performance using the same, namely nucleic acid and proteins or biosensors micronets. The above mentioned compatible solutes are selected from a group that includes Mannosylglycerate (MG) and its 3 derivatives manno-sylglyceramide (MGA), -mannosylglycerol (MGOH), and mannosyl-lactate (MGLac), 1,1-di-glycerol phosphate (DGP), ectoin, hydroxyectoin, and or derivatives or combinations thereof. The improved performance of the above mentioned techniques might be due to: a better state of preservation of the material to be immobilized, increasing the life expectancy of the material, and/or decreasing the storage and/or transport requirements, a more efficient and uniform deposition of the material on the support, more efficiency and/or specificity of hybridation of the marked material, all this originating an increase of the signal-to-noise ratio.Type: ApplicationFiled: February 23, 2007Publication date: March 12, 2009Applicants: STAB VIDA, Investigacao e Servicos em Ciencias Biologicas, Lda, BITOP AGInventors: Jorge Miguel Pereira De Oliveira Da Silva Santos, Catia Machado, Ana Catarina Varela Raposo, Stefano Volinia, Nicoletta Mascellani, Steven John Setford, Elisabeth Loose, Christopher David Maycock, Maria Rita Mendes Bordalo Ventura Centeno Lima, Pedro Lamosa Antonio, Isabel Sequeira Lopes, Helena Santos, Alcino Orfeu De Leao E Flores

Patent number: 7396683Abstract: Measurement of the redox properties of household dust is used to detect the presence of allergen-associated materials. Measurement may be electrochemical, preferably amperometric. A disposable electrode assembly may be made by screen printing with conductive (e.g. carbon and Ag/AgCl) inks. An absorbent pad overlying the electrodes can be used to wipe a surface to collect a sample. It may contain electrolyte and buffer components, so that adding water carries sample in an electrolyte/buffer solution to the electrodes.Type: GrantFiled: November 12, 2001Date of Patent: July 8, 2008Assignee: Cranfield UniversityInventors: John Anthony Bolbot, Steven John Setford, Stephen Frederick White
