<p>A method and a device for controlling, based on electrophoresis, charged particles in liquid. The method comprises: applying a voltage to two electrodes of a microflow device respectively to form a first voltage difference, changing the voltages on the two electrodes to form a second voltage difference after a first time duration, and continuing a second time duration so as to differently move the charged particles in a liquid drop to be measured, thereby enabling the particles to be separated, at least part of the charged particles in the liquid drop to be measured being capable of moving by means of the amplitude of at least one of the first voltage difference and the second voltage difference. By means of effects such as electrowetting, electrophoresis and the like, the operation on a liquid drop can be implemented, and in addition, charged particles suspended in the liquid drop, especially different particles with the same charge can be controlled.</p> |
