title: Stepwise fluorescence changes of quantum dots: single-molecule spectroscopic studies on the properties of turn-on quantum dots.
abstract: Single-molecule spectroscopy of turn-on quantum dots induced by NADPH-dependent biocatalyzed transformations reveals that the fluorescence intensities of quantum dots functionalized with Nile Blue are stepwisely and reversibly changed in the presence of NADPH.
