Cavity-Amplified Scattering Spectroscopy Reveals the Dynamics of Proteins and Nanoparticles in Quasi-transparent and Miniature Samples

Dynamic light scattering techniques are routinely used for numerous industrial and research applications, because they can give access to the motion spectrum of micro- and nano-objects, and therefore to particle sizes or visco-elastic properties. However, measurements are impossible when samples do not scatterer light enough, i.e. when there are too few scattering events due to excessively small scattering cross-sections and/or low...
