| abstract |
Disclosed is a system and method for mixing and transporting fluids in a conventional microfluidic system. In certain embodiments, the fluid includes reagents that can participate in one or more chemical or biological reactions. Some embodiments relate to systems and methods that use one or more vent valves to controllably flow and / or mix portions of fluid in a microfluidic system. Preferably, fluid control, such as fluid flow sequence and / or change in flow velocity, is achieved by opening and closing one or more vent valves and fluid flow operated at substantially constant pressure (eg, (Vacuum) can be applied by applying a single source. This simplifies the operation and use of the device by the intended user. [Selection figure] None |
