PROBLEM TO BE SOLVED: To provide systems and methods for mixing and delivering fluids in normal microfluidic systems.SOLUTION: In a prescribed embodiment, fluids include reagents that can participate in one or more chemical or biological reactions. Some embodiments relate to systems and methods employing one or more vent valves to controllably flow and/or mix portions of the fluid within a microfluidic system. Preferably, fluid control such as a sequence of fluid flow and/or a change in flow rate, can be achieved by opening and closing one or more vent valves and by applying a single source of fluid flow (e.g., a vacuum) operated at a substantially constant pressure. Thereby, an operation and use of a device by an intended user can be simplified. |
