Particle tracking in living cells: a review of the mean square displacement method and beyond
The focus of many particle tracking experiments in the last decade has been active systems, such as living cells. In active systems, the particles undergo simultaneous active and thermally driven
Some Hydrodynamical Aspects of Fish Schooling
Hydrodynamical interactions between fish swimming close to each other in synchronization at equal velocities are examined. An inviscid flow model is employed to show that by proper positioning fish
Rheology and microrheology of natural and reduced-calorie Israeli honeys as a model for high-viscosity Newtonian liquids
Honey is a food biomaterial that has been used as a natural therapeutic agent against infections and to stimulate wound healing; its flow behavior is interesting as it affects processing and
Simulations of complex particle transport in heterogeneous active liquids
Thermal-fluctuation and external force-induced motion of particles provide mechanical and rheological information for viscoelastic liquids and soft solids. Although particle tracking is
Origin of active transport in breast-cancer cells
Insight is provided into mechanisms driving active transport in living cells, using intracellular particle tracking, which shows that the motion in both cell types is actively driven by fluctuating microtubules and their associated molecular motors.
Time-Dependent Micromechanical Responses of Breast Cancer Cells and Adjacent Fibroblasts to Electric Treatment
Direct-current, low-intensity, electric fields were suggested as a minimally invasive treatment for various cancers. The tumor microenvironment may affect treatment efficacy, albeit it has not
Kinetic theory analysis of explosive boiling of a liquid droplet
The process of rapid phase transition from highly superheated liquid to vapor is frequently so fast and violent that it is called explosive boiling. The paper uses the kinetic theory of evaporation
Bio-microrheology: a frontier in microrheology.
This work reviews the current state of the field and discusses the utility and challenges of this emerging approach, termed bio-microrheology, or the study of deformation and flow of biological materials at small length scales, which promises to improve concepts of regional and integrated properties, structures, and transport in live cells.

Experimental evidence of strong anomalous diffusion of polymeric particles internalized into living cancer cells is presented and Bilinearity indicates that particle motion is composed of subdiffusive regimes separated by active yet nonballistic flights.

The study shows that the internal microenvironment of the highly metastatic cells evaluated here is more pliable and their cytoskeleton is less dense than the poorly metastatic and benign cells, revealing intracellular structure and mechanics that can support the unique function and invasive capabilities of highly metastatics cells.
