The more a fluorescent molecule is exposed to a solvent, the faster its triplet excited state is quenched by molecular oxygen. The changes in the solvent accessibility of a fluorescent molecule were probed by measuring the duration of the off time during the blinking of the fluorescence, which enabled analysis of the function of a molecular beacon-type probe.
