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 …

Hamiltonian dynamics and structural states of two-dimensional active particles

Y Shoham, N Oppenheimer - Physical Review Letters, 2023 - APS
We show that a two-dimensional system of flocking active particles interacting
hydrodynamically can be expressed using a Hamiltonian formalism. The Hamiltonian …

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 …

Hydrodynamics of a single filament moving in a spherical membrane

W Shi, M Moradi, E Nazockdast - Physical Review Fluids, 2022 - APS
Dynamic organization of the cytoskeletal filaments and rodlike proteins in the cell membrane
and other biological interfaces occurs in many cellular processes, including cell division …

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 …

The drag of a filament moving in a supported spherical bilayer

W Shi, M Moradi, E Nazockdast - Journal of Fluid Mechanics, 2024 - cambridge.org
Many of the cell membrane's vital functions are achieved by the self-organization of the
proteins and biopolymers embedded in it. The protein dynamics is in part determined by its …

Hydrodynamic aggregation of membrane inclusions due to non-Newtonian surface rheology

V Vig, H Manikantan - Physics of Fluids, 2023 - pubs.aip.org
Biological membranes are self-assembled complex fluid interfaces that host proteins,
molecular motors, and other macromolecules essential for cellular function. These …

Vortex flows and streamline topology in curved biological membranes

R Samanta, N Oppenheimer - Physics of Fluids, 2021 - pubs.aip.org
When considering flows in biological membranes, they are usually treated as flat although,
more often than not, they are curved surfaces, even extremely curved, as in the case of the …

Force dipole interactions in tubular fluid membranes

S Jain, R Samanta - Physics of Fluids, 2023 - pubs.aip.org
We construct viscous fluid flow sourced by a force dipole embedded in a cylindrical fluid
membrane, coupled to external embedding fluids. We find analytic expressions for the flow …
