From the mean-squared displacement (MSD) of the tracers, the bulk rheological and viscometric properties of the host medium can be inferred. Here, the MSD is determined by applying Differential Dynamic Microscopy (DDM). Compared to other microscopy techniques, DDM avoids particle tracking but provides parameters commonly acquired in light scattering experiments. Based on the spatial Fourier transform of image differences, the intermediate scattering function and subsequently the MSD is calculated.
