METHOD FOR CONTROLLING SUBSTANCE MOVING SPEED AND APPARATUS FOR CONTROLLING THE SAME

摘要

The present invention provides a method and apparatus for controlling the moving speed of a substance, both of which can adjust the moving speed of a substance to a desired speed. The control method and control apparatus cause a substance to pass through an internal space, in which an electro-osmotic flow is generated, of a surround electrode formed so as to surround part of the moving path of the substance, whereby the control method and control apparatus change the moving speed of the substance.

主权项

1. A method of controlling substance moving speed, the method comprising the steps of:
causing a substance to move along an electric field formed by an electrode pair; and causing the substance to pass through an internal space of a surround electrode formed so as to surround a part of a movement path of the substance, to thereby change the moving speed of the substance, wherein: the surround electrode is charged only to either one of positive or negative; and a medium having an electrolyte dissolved therein is disposed in the internal space of the surround electrode.
