Among several models for microswimmers, the three-sphere microswimmer proposed by
Najafi and Golestanian captures the essential mechanism for the locomotion of a …

Microrheology is an emerging technique that probes mechanical response of soft material at
micro-scale. Generally, microrheology technique can be divided into active and passive …

We discuss the linear hydrodynamic response of a two-dimensional active chiral
compressible fluid with odd viscosity. The viscosity coefficient represents broken time …

Active diffusion of intracellular components is emerging as an important process in cell
biology. This process is mediated by complex assemblies of molecular motors and …

We discuss hydrodynamic forces acting on a two-dimensional liquid domain that moves
laterally within a supported fluid membrane in the presence of odd viscosity. Since active …

Mechanochemically active enzymes change their shapes within every turnover cycle.
Therefore, they induce circulating flows in the solvent around them and behave as …

A simple model of an active colloid consisting of dumbbell-shaped particles that cyclically
change their length without propelling themselves is proposed and analyzed. At nanoscales …

We discuss the hydrodynamic collective effects due to active protein molecules that are
immersed in lipid bilayer membranes and modeled as stochastic force dipoles. We …

With the use of the “two-fluid model,” we discuss anomalous diffusion induced by active
force dipoles in viscoelastic media. Active force dipoles, such as proteins and bacteria …

Oscillatory active nematics represent nonequilibrium suspensions of microscopic objects,
such as natural or artificial molecular machines, that cyclically change their shapes and thus …
