Active colloids on fluid interfaces

J Deng, M Molaei, NG Chisholm, T Yao, A Read… - Current Opinion in …, 2022 - Elsevier
We review recent work on active colloids at interfaces, including self-propelled colloids that
move by generating a propulsive force, and driven colloids that move under external fields …

Nonequilibrium transport induced by biological nanomachines

Y Hosaka, S Komura - Biophysical Reviews and Letters, 2022 - World Scientific
Biological nanomachines are nanometer-size macromolecular complexes that catalyze
chemical reactions in the presence of substrate molecules. The catalytic functions carried …

Nonreciprocal response of a two-dimensional fluid with odd viscosity

Y Hosaka, S Komura, D Andelman - Physical review E, 2021 - APS
We discuss the linear hydrodynamic response of a two-dimensional active chiral
compressible fluid with odd viscosity. The viscosity coefficient represents broken time …

Hydrodynamic lift of a two-dimensional liquid domain with odd viscosity

Y Hosaka, S Komura, D Andelman - Physical Review E, 2021 - APS
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 …

Sensing the shape of a cell with reaction diffusion and energy minimization

AR Singh, T Leadbetter… - Proceedings of the …, 2022 - National Acad Sciences
Some dividing cells sense their shape by becoming polarized along their long axis. Cell
polarity is controlled in part by polarity proteins, like Rho GTPases, cycling between active …

Tunable collective dynamics of active inclusions in viscous membranes

H Manikantan - Physical review letters, 2020 - APS
We study hydrodynamic interactions and clustering mechanisms of active membrane
inclusions within lipid bilayers. Pairs of inclusions display unique oscillatory dynamics that …

Pair dynamics of active force dipoles in an odd-viscous fluid

Y Hosaka, D Andelman, S Komura - The European Physical Journal E, 2023 - Springer
We discuss the lateral dynamics of two active force dipoles, which interact with each other
via hydrodynamic interactions in a thin fluid layer that is active and chiral. The fluid layer is …

Axisymmetric monopole and dipole flow singularities in proximity of a stationary no-slip plate immersed in a Brinkman fluid

A Daddi-Moussa-Ider, Y Hosaka, A Vilfan… - Physical Review …, 2023 - APS
The Green's function plays an important role in many areas of physical sciences and is a
prime tool for solving diverse hydrodynamic equations in the linear regime. In the present …

Hydrodynamics of an odd active surfer in a chiral fluid

Y Hosaka, R Golestanian… - New Journal of …, 2023 - iopscience.iop.org
We theoretically and computationally study the low-Reynolds-number hydrodynamics of a
linear active microswimmer surfing on a compressible thin fluid layer characterized by an …

Mechanochemical enzymes and protein machines as hydrodynamic force dipoles: the active dimer model

Y Hosaka, S Komura, AS Mikhailov - Soft Matter, 2020 - pubs.rsc.org
Mechanochemically active enzymes change their shapes within every turnover cycle.
Therefore, they induce circulating flows in the solvent around them and behave as …
