2024年10月20日 · Dynamic light scattering (DLS) is a useful tool for the study of the solution-based behavior of colloids and molecular assemblies. The aim of this methods paper is to provide perspective on how this technique can be used by supramolecular chemists.
Dynamic Light Scattering (DLS), sometimes referred to as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering, is a technique classically used for measuring the size of particles typically in the sub-micron region, dispersed in
Dynamic Light Scattering (sometimes referred to as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering) is a technique for measuring the size of particles typically in the sub micron region. DLS measures Brownian motion and relates this to the size of the particles.
Dynamic light scattering measures variation in scattered intensity with time at a fixed scattering angle (typically 90o) ,while static light scattering measures scattered intensity as a function of angle. Time range: typically 10-7 - 103 s! Length range: typically 10-9. 10-6 …
