Fluid mixing and delivery in microfluidic systems
First Claim
1. A fluidic device, comprising:
- a first microfluidic channel comprising an inlet and an outlet;
a first fluid comprising metol and sodium decyl sulfate stored in the first microfluidic channel, wherein the metol is a first reagent for a chemical and/or biological reaction;
a seal covering the inlet of the first microfluidic channel;
a seal covering the outlet of the first microfluidic channel; and
a reaction area for performing a chemical and/or biological reaction.

Abstract
The specification generally discloses systems and methods for mixing and delivering fluids in microfluidic systems. The fluids can contain, in some embodiments 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 fluid within the microfluidic system. Advantageously, 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. This can simplify the operation and use of the device by an intended user.
