20130309778 | ASSAY DEVICE AND READER - The present invention relates to a microfluidic based assay system, comprising a disposable assay cartridge and associated reading device, as well as the individual components themselves. The present invention also relates to methods of conducting assays, using the cartridge and device of the invention, as well as kits for conducting assays. | 11-21-2013 |
20140017709 | MICROFLUIDICS BASED ASSAY DEVICE - A subtractive corrective assay device and methodology, whereby ail required binding and label detection reagents are initially located within the detection zone. Application of a magnetic field is used to selectively remove bound label from the detection zone by means of paramagnetic particles. The relationship between measured label concentration before and after the application of a magnetic field within the detection zone is used to accurately measure analyte concentration within the sample. | 01-16-2014 |

20110053289 | Assay Device and Method - An assay method and device can perform at least one (e.g., at least two) assays on a single aliquot of a sample liquid. The device can mix a sample liquid with assay reagents including magnetically susceptible particles. The device is configured to create a sample liquid-air interface with the sample liquid. The magnetically susceptible particles can be located (via an applied magnetic field) at the liquid-air interface when a second liquid contacts the interface to form a liquid-liquid interface. The magnetic particles travel across the liquid-liquid interface to the second liquid. The magnetically susceptible particles are configured to trans-port an analyte across the interface into the second liquid. An assay for the analyte is performed in the second liquid. An assay for another analyte can also be performed in the sample liquid. | 03-03-2011 |
