Abstract:
1. A centrifugal force-based microfluidic device for extracting a micro element from a material sample, comprising: a body of revolution; at least one microfluidic structure disposed in the body of revolution, wherein the microfluidic structure comprises: a plurality of chambers; a plurality of channels which connect the chambers; and a plurality of valves which are disposed in the channels to control fluid flow, and wherein the microfluidic structure transmits fluid using centrifugal force due to rotational movement of the body of revolution; and micro-particles contained in one of the chambers which capture a target material from the material sample flowing into the chamber, an external energy source configured to irradiate electromagnetic waves onto the micro-particles having the target material, wherein the microfluidic structure is configured to wash the micro-particles having the target material in the chamber, and to separate the micro element from the target material in another chamber by the electromagnetic wave.
