Nanopore Sequencing

A novel technology for sequencing individual DNA molecules using single-channel recording techniques has been conceived. Single molecules of DNA are drawn through a small channel or nanopore that functions as a sensitive detector. The detection schemes being developed will transduce the different chemical and physical properties of each base into a characteristic electronic signal. Nanopore sequencing has the potential of reading very long stretches of DNA at rates exceeding 1 base per millisecond.
