Abstract
The present invention relates to biosensors having improved sample application and measuring properties and their uses for detection, preferably, quantitative measurement, of analyte in a liquid sample. In particular, the invention provides for a biosensor having a sample application and reaction chamber facilitating the speed and uniformity of sample application, especially small volume sample application, via capillary flow. The invention also provides for a biosensor having multiple circuits that lead to improved assay consistency and accuracy. Methods for assaying analytes or enzymes using the biosensors are further provided.
