title: Strand exchange reaction modulated fluorescence "off-on" switching of hybridized DNA duplex stabilized silver nanoclusters.
abstract: The fluorescence (FL)"off-on" switching of designed DNA duplex stabilized silver nanoclusters can be accomplished through the control of DNA strand exchange reaction. The successful sequential control of the FL emission of silver nanoclusters in "off-on" switching cycles confirms that the DNA duplex stabilized silver nanoclusters can work as a new kind of DNA FL switch.
