title: Carbon nanotube-DNA hybrid fluorescent sensor for sensitive and selective detection of mercury(II) ion.
abstract: Mercury ion (Hg(2+)) is able to specifically bind to the thymine-thymine (T-T) base pair in a DNA duplex and single-walled carbon nanotubes (SWNTs) can effectively quench fluorescence of the dye tethered to the DNA, which enables fluorescent detection of Hg(2+) in aqueous solution with high selectivity and sensitivity.
