Abstract:In this study, we show that the characteristic narrow fluorescence emission spectra of CdSe/ZnS quantum dots can be distinguished from the endogenous fluorescence from Daphnia magna and their food source (spirulina) and used to localize QDs in exposed D. magna using laser scanning fluorescence microscopy.
