A fluorescence\u2010sensing system based on the photoinduced electron transfer (PET) of (mono\u20106\u2010thio\u2010\u03b2\u2010CD)\u2013CdTe QDs was then designed to measure the interaction of phenothiazine dyes [methylene blue (MB) and methylene green (MG)] with herring sperm DNA (hsDNA). This fluorescence\u2010sensing system was based on a fluorescence \u201cOFF\u2013ON\u201d mode. First, MB\/MG adsorbed on the surface of (mono\u20106\u2010thio\u2010\u03b2\u2010CD)\u2013CdTe QDs effectively quenches the fluorescence of (mono\u20106\u2010thio\u2010\u03b2\u2010CD)\u2013CdTe QDs through PET. Then, addition of hsDNA restores the fluorescence intensity of (mono\u20106\u2010thio\u2010\u03b2\u2010CD)\u2013CdTe QDs, because hsDNA can bind with MB\/MG and remove it from the as\u2010prepared (mono\u20106\u2010thio\u2010\u03b2\u2010CD)\u2013CdTe QDs. In addition, detailed reaction mechanisms of the (mono\u20106\u2010thio\u2010\u03b2\u2010CD)\u2013CdTe QDs\u2013MB\/MG\u2013hsDNA solution system were studied using optical methods, by comparison with the TGA\u2013CdTe QDs\u2013MB\/MG\u2013hsDNA solution system.
