the complex of fDNA (10 mL, 10nM) with GO (35 mL,1 mg/mL ) wasinvestigated by addition of cDNA (10 mL, 10nM), which led to therecovering of fluorescence of fDNA by duplex formation and releasing of fDNA from GO.The kinetic of desorbing was investigatedby measurement of emission spectra at different times ,and 10 minwas determined as optimum time needed for duplex formation

The complex of fDNA (10 mL 10nM), with GO (35, mL 1 mg / mL was.)Investigated by addition of cDNA (10, mL 10nM), which led to the.Recovering of fluorescence of fDNA by duplex formation and.Releasing of fDNA from GO.The kinetic of desorbing was investigated.By measurement of emission spectra at different times and 10, min.Was determined as optimum time needed for duplex formation.
