Patent number: 9347931Abstract: The present invention is directed to a lateral flow assay device for the monitoring and measuring of coagulation and method thereof. Ideally, the invention is directed to a lateral capillary flow device for the monitoring and/or measurement of coagulation in a liquid sample wherein the device comprises a non-porous substrate with a zone for receiving a sample and a defined flow path zone wherein a clotting agent is deposited on at least part of the defined flow path zone to accelerate the coagulation of the liquid sample, enable the formation of an evenly distributed clot along the defined flow path zone and to result in the change in flow rate or cessation of flow of the liquid sample along the defined flow path zone.Type: GrantFiled: April 23, 2010Date of Patent: May 24, 2016Assignees: DUBLIN CITY UNIVERSITY, ÅMIC ABInventors: Anthony Joseph Killard, Magdalena Maria Dudek, Brian MacCraith, Ib Mendel-Hartvig, Ove Öhman

Patent number: 9291558Abstract: A sensor comprising a substrate (100) having a first surface (105) and a second surface (110) is described. The first surface has at least one sensor site (115) provided thereon. The substrate is configured such that on excitation of a sample provided at the sensor site, luminescence originating from the sensor site propagates into the substrate, the second surface of the substrate being configured to selectively transmit the luminescence propagating within the substrates at angles greater than the critical angle out of the substrate where it may be detected by a detector (160) provided below the substrate.Type: GrantFiled: May 11, 2011Date of Patent: March 22, 2016Assignees: Dublin City University, Amic ABInventors: Jim Writser Peter Bakker, Ove Ohman, Dirk Kurzbuch, Thomas Ruckstuhl, Brian MacCraith, Stephen O'Driscoll

Patent number: 7750316Abstract: This present disclosure provides an optical chip for fluorescence detection. The optical chip has one or more parabolic optical elements that capture and collimate the fluorescent light and direct it onto a detector. The optical chip may be constructed of a polymer and made using injection molding techniques.Type: GrantFiled: May 10, 2006Date of Patent: July 6, 2010Assignee: Dublin City UniversityInventors: Brian MacCraith, Thomas Ruckstuhl

Patent number: 7655475Abstract: The invention provides a luminescent based sensor having a luminescent material optically coupled to a substrate, and adapted to be used in a medium or environment such as water or air. A detector is provided to detect light that is emitted into the substrate by the material. The substrate is adapted to redirect light that is emitted into the substrate at angles with the range ?esc ? ? ? ?lsc where ?esc is the critical angle of the environment/substrate interface and ?lsc is the critical angle of the luminescent layer/substrate interface. Examples of possible configurations are described.Type: GrantFiled: January 23, 2002Date of Patent: February 2, 2010Assignee: Fluorocap LimitedInventors: Brian MacCraith, Lubos Polerecky

Publication number: 20060257094Abstract: Improved carbon dioxide sensors are disclosed which are less sensitive to the moisture content of the environment and which are substantially insensitive to oxygen levels under normal working conditions. The CO2 sensor comprises a pH indicator and long-lived reference luminophore and a porous sol-gel matrix. Combined CO2 and O2sensors are also described. Further disclose are methods of printing sensor onto substrates.Type: ApplicationFiled: February 27, 2004Publication date: November 16, 2006Applicant: Gas Sensors Solutions LimitedInventors: Aisling McEvoy, Brian MacCraith, Colette McDonagh, Christoph Von Bultzingslowen, Olive Von Bultzingslowen

Publication number: 20050009198Abstract: A luminescence-based sensor assembly is described. The sensor assembly utilizes the angular propagation of light into a substrate to distinguish between light originating from a luminescent source close to the substrate and that from a source further away from the substrate. Utilizing such a technique, it is possible to employ direct illumination of the sources of luminescence.Type: ApplicationFiled: September 11, 2002Publication date: January 13, 2005Inventors: Brian MacCraith, Lubos Polerecky
