Abstract
The present invention provides a micro liquid control system which, adopting a method to flow a fine target object such as droplets together with a main liquid, allows high speed, large quantity processing for sorting the target object such as the droplets. The system comprises a microchannel, which includes a main channel to flow the main liquid in which the fine target object is dispersed and a sorting channel to sort the target object at the downstream side of the main channel, and a target object selecting means, which selects the target object flowing in the microchannel and supply it to the sorting channel. The target object selecting means comprises electrodes on which the voltage of the same polarity or the opposite polarity is applied to move and select the target object with the attractive or repulsive force.
