Dynamic Light Scattering is a useful and popular technique to characterize nano-scale particles and macromolecules. In combination with Acoustic Spectroscopy Zeta Potential analysis, DLS provides a powerful solution for determining stability and function. We will discuss the techniques of DLS and Acoustic Zeta Potential as well as investigate and interpret data obtained on the HORIBA LB-550 and DT-300 analyzers.

Topics covered include:

• Why particle size is important for small particles/macromolecules
• Why zeta potential is a useful indicator of stability
• An introduction to DLS and Acoustic Spectroscopy
• Data interpretation of a typical protein
