Abstract:
A method of controllably moving material in a microfluidic device, comprising:providing a microfluidic device that includes a body having at least first, second, third and fourth channels disposed therein, the first, second, third and fourth channels communicating at a first intersection, the first channel connecting at least a first material source to the first intersection;applying a first voltage difference between the first material source and the second channel to move the first material from the first channel, through the intersection and into the second channel;applying a second voltage difference between the third channel and the first intersection, and a third voltage difference between the fourth channel and the first intersection simultaneously with the applying of the first voltage difference, to direct movement of the first material through the intersection into the second channel.
