We present a thermokinetic description of anomalous diffusion of single particles and
clusters in a viscoelastic medium in terms of a non-Markovian diffusion equation involving
memory functions. The scaling behavior of these functions is analyzed by considering
hydrodynamics and cluster-size space random walk arguments. We explain experimental
results on diffusion of Brownian particles in the cytoskeleton, in cluster− cluster aggregation,
and in a suspension of micelles.
