We study the motion of a probe driven by microtubule-associated motors within a living
eukaryotic cell. The measured mean square displacement,< x (t) 2> of engulfed 2 and 3 μ m …

We show that within a living eukaryotic cell, mean square displacement of an engulfed
microsphere shows enhanced diffusion scaling as t 3/2 at short times, with a clear crossover …

The cellular cytoskeleton is a fascinating active network, in which Brownian motion is
intercepted by distinct phases of active transport. We present a time-resolved statistical …

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 …

The discovery of anomalous diffusion of larger biopolymers and submicron tracers such as
endogenous granules, organelles, or virus capsids in living cells, attributed to the …

The results of mechanical measurements on single cultured epithelial cells using both
magnetic twisting cytometry (MTC) and laser tracking microrheology (LTM) are described …

Intracellular transport is a complex interplay of ballistic transport along filaments and of
diffusive motion, reliably delivering material and allowing for cell differentiation, migration …

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

A ubiquitous observation in cell biology is that the diffusive motion of macromolecules and
organelles is anomalous, and a description simply based on the conventional diffusion …

Recent experiments reveal both passive subdiffusion of various nanoparticles and
anomalous active transport of such particles by molecular motors in the molecularly crowded …
