We proposed a new DNA detection method based on microbeads dielectrophoresis (DEP). In the method, the DNA-labeled microbeads are electrically detected. Only the DNA-labeled microbeads are trapped on a microelectrode by positive DEP, whereas the pristine ones are repelled In this paper, size selective detection of DNA using the method is described. It was found that the frequency response of DEP of the DNA-labeled microbeads depended on the DNA length. At high frequency only the long DNA-labeled microbeads were trapped, whereas the short DNA-labeled microbeads were repelled. This phenomena can realize selective detection of DNA with different length.
