摘要:
A microfluidic structure in which a plurality of chambers arranged at different positions are connected in parallel and into which a fixed amount of fluid may be efficiently distributed without using a separate driving source, and a microfluidic device having the same. The microfluidic device includes a platform having a center of rotation and including at least one microfluidic structure. The microfluidic structure includes a sample supply chamber configured to accommodate a sample, a plurality of first chambers arranged in a circumferential direction of the platform at different distances from the center of rotation of the platform, and a plurality of siphon channels, each of the siphon channels being connected to a corresponding one of the first chambers.
摘要:
A diagnostic assay system including a test device and a scanning device are described. In one implementation, the scanning device includes a source of electromagnetic radiation, an optics assembly, a detector, and a microprocessor disposed within a chassis. The test device and scanning device may be configured to be movable relative to each other during operation of the scanning device.

The present invention is directed to methods and apparatus for detection of one or more analytes. Analytes include agents or components of infectious agents such as pathogenic virus, as well as enzymes, proteins and biomarkers.
摘要:
A method for determining whether a subject has had a stroke and, if so, the type of stroke which includes analyzing the subject's body fluid for at least four selected markers of stroke, namely, myelin basic protein, S100 protein, neuronal specific enolase and a brain endothelial membrane protein such as thrombomodulin or a similar molecule. The data obtained from the analyses provide information as to the type of stroke, the onset of occurrence and the extent of brain damage and allow a physician to determine quickly the type of treatment required by the subject.
摘要:
The present invention provides an apparatus for retaining solid state reagents and/or for processing sample for a diagnostic test, where the apparatus avoids liquid “hang-up” that would otherwise result in loss of sample or fluid volume during sample transfer. The invention further provides diagnostic methods that employ the apparatus, so as to provide sensitive and accurate analyte detection.
