Diffusion in aqueous solutions containing disaccharides using laser techniques

The application of laser techniques to assess transport properties of liquids using fluorescent molecules to trace translational or rotational diffusion has become an efficient and versatile tool nowadays. This work reports the experimental set up and preliminary runs of an optical device to measure...
