| abstract |
A method and apparatus for microfluidic analysis applied to the analysis of various biological and chemical compositions. A microliter liquid sample, particularly a biological sample, is analyzed in a device that uses centrifugal and capillary forces. The sample is moved by capillary force to one or more metering wells that define the amount of sample to be analyzed in subsequent steps. A defined amount of sample travels from the metering well to one or more conditioning and reagent wells that measure the amount of analyte contained in each metered sample. [Selection figure] None |
