Fluorescent dyes are non-protein molecules that absorb light and re-emit it at a longer wavelength. They are often used in the fluorescent labelling of biomolecules and can be smaller or more ...

Fluorescence imaging can be conducted with long Stokes shift dyes that minimize crosstalk between the excitation source and fluorescent emission to improve the signal-to-background ratio.

Water in the Sydney Harbour in New South Wales, Australia, turned a bright green colour due to the spillage of a non-toxic ...

To visualize this in a flow, we could imagine the motion of a small marked element of fluid. For example, we could mark a drop of water with fluorescent dye and illuminate it using a laser so that it ...
