Significance Elastic filaments and semiflexible polymers occur ubiquitously in biophysical systems and are key components of many complex fluids, yet our understanding of their conformational dynamics under flow is incomplete. Here, we report on experimental observations of actin filaments in simple shear and characterize their various dynamical regimes from tumbling to buckling and snaking. Numerical simulations accounting for elastohydrodynamics as well as Brownian fluctuations show perfect…

Dynamics of flexible filaments in oscillatory shear flows

The fluid-structure interactions between flexible fibers and viscous flows play an essential role in various biological phenomena, medical problems, and industrial processes. Of particular interest is

Flow-Induced Buckling of Elastic Microfilaments with Non-Uniform Bending Stiffness

Buckling plays a critical role in the transport and dynamics of elastic microfilaments in Stokesian fluids. However, previous work has only considered filaments with homogeneous structural properties.

Chirality-induced bacterial rheotaxis in bulk shear flows

Combining experimental, numerical, and theoretical analysis, a comprehensive study of the transport of motile bacteria in shear flows reveals the scaling laws behind the average rheotactic velocity at moderate shear rates using a chirality parameter and explains the reorientation dynamics leading to saturation at largeShear rates from the marginal stability of a fixed point.

Flexible filaments buckle into helicoidal shapes in strong compressional flows

The occurrence of coiled or helical morphologies is common in nature, from plant roots to DNA packaging into viral capsids, as well as in applications such as oil drilling processes. In many

Conformational and Dynamical Evolution of Block Copolymers in Shear Flow

Conformation and dynamical evolution of block copolymers in shear flow is an important topic in polymer physics that underscores the forming process of various materials. We explored deformation and

Chaos and irreversibility of a flexible filament in periodically driven Stokes flow.

The flow of Newtonian fluid at low Reynolds number is, in general, regular and time-reversible due to absence of nonlinear effects. For example, if the fluid is sheared by its boundary motion that is

Dynamics of electrospun hydrogel filaments in oscillatory microchannel flows: A theoretical and experimental approach

The dynamics of highly flexible micro- and nano-filaments are important to a variety of biological, medical, and industrial problems. The filament configuration variation and cross-stream migration

Trapping, gliding, vaulting: transport of semiflexible polymers in periodic post arrays.

This work analyzes the dynamics of semiflexible polymers under the influence of an imposed flow in a structured two-dimensional lattice serving as an idealization of a porous medium and identifies three dominant modes of transport that involve trapping, gliding and vaulting of the polymers around the obstacles.



Direct visualization of flow-induced conformational transitions of single actin filaments in entangled solutions.

It is shown that initially entangled filaments form disentangled orientationally ordered hairpins, confined in the flow-vorticity plane, which explains the strain-softening and shear-thinning behaviour of entangled F-actin solutions, which aids the understanding of the flow behaviour of complex fluids containing semi-flexible polymers.

Dynamics of a semiflexible polymer or polymer ring in shear flow.

This work performs extensive Brownian dynamics simulations to explore the tumbling dynamics of semiflexible polymers over a broad range of shear strength and the polymer's persistence length l(p), and finds that the Weissenberg number alone does not suffice to fully characterize the tumbled dynamics, and the classical scaling law breaks down.

The dynamics and transport properties of Brownian semiflexible filaments suspended in a two-dimensional array of counter-rotating Taylor-Green vortices are investigated using numerical simulations

We study, using both experiment and theory, the coupling of transport and shape dynamics for elastomeric fibres moving through an inhomogeneous flow. The cellular flow, created electromagnetically in

Direct observation of the dynamics of semiflexible polymers in shear flow.

This work directly determines the configurational dynamics of individual actin filaments with varying lengths in a well defined shear geometry by combining microscopy, microfluidics, and a semiautomated moving stage.

Fluctuations, dynamics, and the stretch-coil transition of single actin filaments in extensional flows.

Using a microfluidic cross-flow geometry, this work verifies predictions of a fluctuation-rounded stretch-coil transition of actin filaments near hyperbolic stagnation points, which show suppressed thermal fluctuations in the extensional regime and a buckling instability under compression.
