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 …

Fractional dynamics has experienced a firm upswing during the past few years, having been
forged into a mature framework in the theory of stochastic processes. A large number of …

This review examines intermittent target search strategies, which combine phases of slow
motion, allowing the searcher to detect the target, and phases of fast motion during which …

We track the motion of individual fluorescently labeled mRNA molecules inside live E. coli
cells. We find that the motion is subdiffusive, with an exponent that is robust to physiological …

We have studied the diffusion of tracer proteins in highly concentrated random-coil polymer
and globular protein solutions imitating the crowded conditions encountered in cellular …

Research on soft materials, including colloidal suspensions, glasses, pastes, emulsions,
foams, polymer networks, liquid crystals, granular materials, and cells, has captured the …

We demonstrate the non-ergodicity of a simple Markovian stochastic process with space-
dependent diffusion coefficient D (x). For power-law forms D (x)≃| x| α, this process yields …

We report the first measurements of the intrinsic strain fluctuations of living cells using a
recently developed tracer correlation technique along with a theoretical framework for …

The translational motion of small molecules in cells appears to be suppressed compared to
what is observed in dilute solutions. Although, the rotation of small proteins is almost …

We review the combinations of optical micro‐manipulation with other techniques and their
classical and emerging applications to non‐contact optical separation and sorting of micro …
