Fluorescence Fidelity Depends on Filters
... often problematic, autofluorescence can be useful in the detection of biological species. Cells containing molecules such as pyridine (NAD, NADP) and flavin (FMN, FAD), which emit fluorescence photons when excited by UV or short-wavelength visible light, can serve as important diagnostic indicators. ...

... Recently, vortices in a Bose-Einstein condensate have been realized experimentally and are currently under intensive study [3, 4, 7]. In most of this work, vortices were identified by observing the density depletion at the cores. The velocity field was inferred only indirectly, with the exception o ...
