    摘要： In various embodiments, a pump is provided that includes a microfluidic channel and a plurality of electrodes for electrostatically translating a target fluid along the channel from an inlet to an outlet. In other embodiments, a valve includes a microfluidic channel, a reservoir in fluidic communication with the channel, and an electrode for electrostatically drawing a fluid from the reservoir into the channel so as to block the flow of other fluids through the channel.

    摘要： A centrifugal force-based microfluidic device for nucleic acid extraction and a microfluidic system are provided. The microfluidic device includes a body of revolution; a microfluidic structure disposed in the body of revolution, the microfluidic structure including a plurality of chambers, channels connecting the chambers, and valves disposed in the channels to control fluid flow, the microfluidic structure transmitting the fluid using centrifugal force due to rotation of the body of revolution; and magnetic beads contained in one of the chambers which collect a target material from a biomaterial sample flowing into the chamber, wherein the microfluidic structure washes the magnetic beads which collect the target material, and separates nucleic acid by electromagnetic wave irradiation from an external energy source to the magnetic beads. The microfluidic system includes the microfluidic device; a rotation operating unit which rotates the body of revolution; and an external energy source which irradiates electromagnetic waves.
