title: Electrochemiluminescence detection of near single DNA molecules by using quantum dots-dendrimer nanocomposites for signal amplification.
abstract: An ultrasensitive electrochemiluminescent biosensor was developed for detection of near single DNA molecules with a linear range of 7 orders of magnitude by combining the specific recognition of a molecular beacon with signal amplification of quantum dots-dendrimer nanocomposites.
