Abstract
A method and apparatus are presented for a microscopic valve. The valve is electronically activated. Sensors for detecting objects in the flow may be external or formed in the channels of the valve. Many valves can be formed in parallel and in sequence on a single substrate. Multiple channels may feed each junction. Closure of the valve is accomplished by the formation of a vapor bubble or bubbles. Virtual walls may be formed by a sequence of bubbles. Logic and driver circuitry for producing bubbles may be external or included in the substrate. Such an array is ideally suited for sorting cells. Other materials in a suspension may also be sorted by a variety of criteria. A multi lumen output can produce a continuous distribution of cells or particles thus sorted.
