Binding fullerenol C(60)(OH)(24) to dsDNA.
The first C(60)(OH)(24)-DNA complex and its fluorescence enhancement is reported. The enhanced fluorescence intensity of fullerenol C(60)(OH)(24) is in proportion to the concentration of DNA in the range of 1 x 10(-9) to 8 x 10(-5) molL(-1) and the detection limit was 1.3 ng mL(-1). Fullerenol C(60)(OH)(24) binds significantly to the phosphate backbone of native dsDNA and to base-pairs within the major groove of sodium salt of dsDNA.
