Abstract
Devices, systems, and methods for charging fluids are disclosed. The charging of fluids improves the mixing of fluids in microfluidic systems. The charging is performed by producing an ion field between an ionizing electrode and an opposed ground electrode. A fluid-containing vessel is positioned between the opposed electrodes and the ion field charges the fluid in the vessel.
Claims25
A fluid charging system comprising:
- an ionizing electrode positioned adjacent to a fluid vessel;
- a ground electrode positioned adjacent to the fluid vessel, the fluid vessel positioned between the ionizing electrode and the ground electrode;
- wherein the ionizing electrode and the ground electrode are configured to produce an ion field that charges fluid contained in the fluid vessel;
- a fluid sampling device configured to withdraw fluid from the fluid vessel;
- and
- a liquid bridge in fluid communication with the fluid sampling device, wherein the liquid bridge comprises:
- (i) a first inlet port in fluid communication with the fluid sampling device, and (ii) a second inlet port in fluid communication with a source of immiscible carrier fluid;
- wherein the liquid bridge is configured to form liquid droplets, and wherein the liquid droplets contain the fluid from the fluid vessel and are enveloped within the immiscible carrier fluid.
