    摘要： Provided is a microfluidic valve, a method of manufacturing the microfluidic valve, and a microfluidic device that employs the microfluidic valve. The microfluidic valve includes a platform that includes two substrates combined facing each other; a channel having a first depth allowing a fluid to flow between the two substrates; a valve gap that is disposed on at least a region of the channel and has a second depth which is smaller than the first depth; and a valve plug that is disposed to fill the valve gap and is formed of a valve material made by mixing a phase change material, which is solid at room temperature, with a plurality of exothermic particles that emit an amount of heat sufficient to melt the phase change material by absorbing electromagnetic waves.

    摘要： Provided are a pump unit and a centrifugal microfluidic system including the pump unit. The pump unit includes a gas generating agent. The gas generating agent includes a plurality of heating particles generating heat by absorbing energy and one of a sublimation material, azide, and azo compound mixed with the heating particles. When energy is supplied to the gas generating agent, the gas generating agent generates gas due to heat emitted from the heating particles to increase an air pressure around the gas generation agent so that the fluid is moved by the increased air pressure.

    摘要： Provided is a method of purifying nucleic acids using a metal-ligand complex, the method comprising: immobilizing the metal-ligand complex on a solid support; bringing a sample containing the nucleic acid into contact with the immobilized complex on the solid support to bind the nucleic acid to the complex; and adding a solution containing a chelate capable of removing the metal to elute the nucleic acid bound to the complex. The nucleic acids can be efficiently purified using a metal-ligand complex interacting with a base of the nucleic acid instead of interacting with a phosphoric acid of the nucleic acid to selectively bind the nucleic acid, and using a chelator capable of removing the metal to elute the nucleic acid.
