1. A method of controlling electroosmotic flow in microfluidic devices, comprising:
- providing a body structure comprising a first microchannel having first and second ends, a plurality of reservoirs in fluid communication with said microchannel, a first and second electrode positioned to apply electrical energy across the first microchannel, a first structure disposed between said first electrode and said first microchannel that reduces fluid flow between said first electrode and said first microchannel; and
applying an electrical current to contents of the first microchannel.
