Traffic-like collective movements are observed at almost all levels of biological systems.
Molecular motor proteins like, for example, kinesin and dynein, which are the vehicles of …

The more we learn about the cytoplasm of cells, the more we realize that the cytoplasm is
not uniform but instead is highly inhomogeneous. In any inhomogeneous solution, there are …

We evaluated the transport of polymeric particles internalized into living cancer cells. The
mean-square displacement demonstrates superdiffusion with a scaling exponent of 1.25 …

In vivo measurements of the passive movements of biomolecules or vesicles in cells
consistently report “anomalous diffusion,” where mean-squared displacements scale as a …

It is well established that a wide variety of phenomena in cellular and molecular biology
involve anomalous transport eg the statistics for the motility of cells and molecules are …

The cellular cytoplasm is a complex, heterogeneous environment (both spatially and
temporally) that exhibits viscoelastic behavior. To further develop our quantitative insight into …

The cell cytoskeleton is a striking example of an 'active'medium driven out-of-equilibrium by
ATP hydrolysis. Such activity has been shown to have a spectacular impact on the …

Diffusion-mediated searching for interaction partners is an ubiquitous process in cell
biology. Transcription factors, for example, search specific DNA sequences, signaling …

Experimental studies of the diffusion of biomolecules within biological cells are routinely
confronted with multiple sources of stochasticity, whose identification renders the detailed …

The crowded intracellular environment poses a formidable challenge to experimental and
theoretical analyses of intracellular transport mechanisms. Our measurements of single …
