Abstract
An apparatus for regulating salt concentration, a lab-on-a-chip including the same and a method of regulating salt concentration using the apparatus are provided. The apparatus includes: a reaction chamber that is defined by a cation exchange membrane and an anion exchange membrane and is selected from the group consisting of a biomolecule extraction chamber, an amplification chamber, a hybridization chamber, and a detection chamber; a first electrode chamber that is defined by the anion exchange membrane and a first electrode and includes an ion exchange medium; and a second electrode chamber that is defined by the cation exchange membrane and a second electrode and includes an ion exchange medium. Even without injecting solutions with different salt concentrations into the reaction chamber by operating pumps and valves for each operation stage, the salt concentration can be reversibly regulated in situ by adjusting the polarity, intensity and application time of a voltage.
