Molecular transport in living systems regulates numerous processes underlying biological
function. Although many cellular components exhibit anomalous diffusion, only recently has …

All substances exhibit constant random motion at the microscopic scale. This is a direct
consequence of thermal agitation, and leads to diffusion of molecules and small particles in …

Diffusion in the plasma membrane of living cells is often found to display anomalous
dynamics. However, the mechanism underlying this diffusion pattern remains highly …

Diffusion plays a crucial role in many biological processes including signaling, cellular
organization, transport mechanisms, and more. Direct observation of molecular movement …

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

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

Stochastic motion on the surface of living cells is critical to promote molecular encounters
that are necessary for multiple cellular processes. Often the complexity of the cell …

Migrating cells in physiological processes, including development, homeostasis and cancer,
encounter structured environments and are forced to overcome physical obstacles. Yet, the …

Protein lateral mobility in cell membranes is generally measured using fluorescence
photobleaching recovery (FPR). Since the development of this technique, the data have …

In cell membranes, proteins and lipids diffuse in a highly crowded and heterogeneous
landscape, where aggregates and dense domains of proteins or lipids obstruct the path of …
