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 …

Individual proteins and protein complexes undergo various motion types, including free
diffusion, confinement, subdiffusion and directed motion. Different motion behaviours reflect …

Nanosized mesoporous silica particles with high colloidal stability attract growing attention
as drug delivery systems for targeted cancer treatment and as bioimaging devices. This …

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 …

We quantitatively analyzed particle tracking data on insulin granules expressing fluorescent
fusion proteins in MIN6 cells to better understand the motions contributing to intracellular …

Diffusion of tracer particles in the cytoplasm of mammalian cells is often anomalous with a
marked heterogeneity even within individual particle trajectories. Despite considerable …

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 …

Eukaryotic cells face the challenging task of transporting a variety of particles through the
complex intracellular milieu in order to deliver, distribute, and mix the many components that …

We present a scaling formula for size-dependent viscosity coefficients for proteins, polymers,
and fluorescent dyes diffusing in complex liquids. The formula was used to analyze the …

Highly sensitive fluorescence microscopy techniques allow single nanoparticles to be
tracked during their uptake into living cells with high temporal and spatial resolution. From …
