DLS Microrheology


Beside its standard applications, nowadays, Dynamic Light Scattering is employed also to investigate rheological porperties of soft matter by means of microrheology.

In analogy to DWS Microrheology, the mean square displacement of tracer particles is extracted using Dynamic Light Scattering (DLS). The spatial resolution is about as low as for microscopy-based microrheology. As a consequence, DLS microrheology can only be used for samples with low viscosity where tracer particles can displace over significant distances. The main advantage compared to microscopy-based microrheology is that the measurements and data treatment are straight forward and fast.
