Abstract
New high density microfluidic devices and methods provide precise metering of fluid volumes and efficient mixing of the metered volumes. A first solution is introduced into a segment of a flow channel in fluidic communication with a reaction chamber. A second solution is flowed through the segment so that the first solution is displaced into the reaction chamber, and a volume of the second solution enters the chamber. The chamber can then be isolated and reactions within the chamber can be initiated and/or detected. High throughput methods of genetic analysis can be carried out with greater accuracy than previously available.
