20110180604 | AUTOMATIC INFORMATION TRANSFER BY COLOR ENCODED FIELDS - Disclosed herein are methods and systems of transferring information from a test strip or an element to a user or an instrumentation using at least one color encoded field. Also disclosed are methods and systems of transferring information from a batch of test strips or entities to a user or an instrumentation, wherein the batch can comprise an extra information carrying entity which can carry extensive information, and the rest entities which can comprise simplified information, such as a link information which can link the entities to the extensive information. | 07-28-2011 |
20100252452 | APPARATUS AND METHOD FOR ELECTROCHEMICAL DETECTION - The present invention is directed to a sensor with opposing electrodes and test strips using this sensor. The invention can be used to measure blood or plasma coagulation in assays like prothrombin time (PT) and thrombin potential, for example, in point-of-care monitoring of anticoagulants. | 10-07-2010 |
20100006452 | Biosensor Apparatus and Methods of Use - Disclosed herein are methods and devices for detecting the presence of an analyte of interest. A biosensor device can include a reaction chamber and an electrochemical detection chamber. The reaction chamber can include at least one immobilized binding site and a probe conjugate adapted to bind to at least one of the target analyte and the immobilized binding site while the detection chamber can include electrodes for detecting an electrochemical reaction. If present, the target analyte in the fluid sample results in a change in the amount of probe conjugate bound in the reaction chamber, which can be detected electrochemically in the detection chamber. | 01-14-2010 |
20090305431 | FLUID TRANSFER MECHANISM - A microfluidic device for transferring liquid from a first chamber to a second chamber is provided. The device has a first chamber; a second chamber; and a barrier between the first chamber and the second chamber, the barrier having least one opening fluidly connecting the first chamber to the second chamber, the at least one opening being sized such that a retention force, such as surface tension, keeps the liquid in the first chamber. The fluid is transferred from the first chamber to the second chamber when an initiation input such as fluid pressure is introduced to the liquid that is sufficient to overcome the retention force. The device may be a sensor strip. | 12-10-2009 |
20090301901 | ELECTROCHEMICAL DETECTION OF MAGNETIC PARTICLE MOBILITY - An exemplary embodiment of the invention may include a method for electrochemically monitoring the mobility of particles in a fluid in response to an external field, the method may include monitoring an electrical characteristic of the fluid in an electrochemical cell, the fluid comprising particles that can be moved under the influence of an externally applied field; observing changes in the electrical characteristic caused by particle movement induced by the external field; and inferring a change in the physical state of the fluid from a change in the magnitude of the electrical characteristic observed. | 12-10-2009 |
20080223732 | Electrochemical detection method - There is disclosed a method of measuring formation of a barrier to restrict or reduce movement of an electroactive species. The method comprises providing an electrochemical cell having a working electrode and a counter electrode spaced from the working electrode, providing a subject component, a testing component and at least one electroactive species within the cell, the subject and testing components being intended to cause the formation of a barrier to restrict or reduce movement of an electroactive species, applying a potential between the working electrode and the counter electrode sufficient to produce a current proportional to the concentration of the electroactive species being measured, and measuring the current at the working electrode to obtain a measure of the formation of the barrier to restrict or reduce movement of the electroactive species. | 09-18-2008 |
