Designing corrugated surfaces to guide colloidal self-assembly
Dinesh Kumar Sahu, Jude Ann Vishnu, Lisa Shafroth +3
The self-assembly of colloidal particles enables the creation of structured materials with programmable functionalities; however, controlling interaction specificity and aggregate…
A microfluidic band-pass filter for flexible fiber separation
Li Zhibo, Bielinski Clément, Lindner Anke +2
The control of particle trajectories in structured microfluidic environments has significantly advanced sorting technologies, most notably through deterministic lateral displacemen…
Dynamics of rigid fibers interacting with triangular obstacles in microchannel flows
Zhibo Li, Clément Bielinski, Anke Lindner +2
Fiber suspensions flowing in structured media are encountered in many biological and industrial systems. Interactions between fibers and the transporting flow as well as fiber cont…
Asymmetric bistability of chiral particle orientation in viscous shear flows
Andreas Zöttl, Francesca Tesser, Daiki Matsunaga +3
The migration of helical particles in viscous shear flows plays a crucial role in chiral particle sorting. Attaching a non-chiral head to a helical particle leads to a rheotactic t…
Pitch Controls the Flexibility of Helical Ribbons
Lucas Prévost, Anke Lindner, Olivia du Roure
Helical objects are often implemented in electronic or mechanical micro-systems, requiring a precise understanding of their mechanical properties. While helices formed by cylindric…
Dynamics of flexible filaments in oscillatory shear flows
Francesco Bonacci, Brato Chakrabarti, David Saintillan +2
The fluid-structure interactions between flexible fibers and viscous flows play an essential role in various biological phenomena, medical problems, and industrial processes. Of pa…
Shaping Nanoscale Ribbons into Micro-Helices of Controllable Radius and Pitch
Lucas Prévost, Dylan M. Barber, Marine Daïeff +5
We report fabrication of highly flexible micron-sized helices from nanometer-thick ribbons. Building upon the helical coiling of such ultra-thin ribbons mediated by surface tension…
Fiber buckling in confined viscous flows: an absolute instability described by the Ginzburg-Landau equation
Jean Cappello, Olivia du Roure, François Gallaire +2
We explore the dynamics of a flexible fiber transported by a viscous flow in a Hele-Shaw cell of height comparable to the fiber height. We show that long fibers aligned with the fl…
Programmed Wrapping and Assembly of Droplets with Mesoscale Polymers
Dylan M. Barber, Zhefei Yang, Lucas Prevost +4
Nature is remarkably adept at using interfaces to build structures, encapsulate reagents, and regulate biological processes. Inspired by Nature, we describe flexible polymer-based…
Signatures of elastoviscous buckling in the dilute rheology of stiff polymers
Brato Chakrabarti, Yanan Liu, Olivia du Roure +2
As a stiff polymer tumbles in shear flow, it experiences compressive viscous forces that can cause it to buckle and undergo a sequence of morphological transitions with increasing…
Optimised hyperbolic microchannels for the mechanical characterisation of bio-particles
Yanan Liu, Konstantinos Zografos, Joana Fidalgo +8
The transport of bio-particles in viscous flows exhibits a rich variety of dynamical behaviour, such as morphological transitions, complex orientation dynamics or deformations. Cha…
Microfluidic In Situ Measurement of Poisson's Ratio of Hydrogels
Jean Cappello, Vincent d'Herbemont, Anke Lindner +1
Being able to precisely characterize the mechanical properties of soft microparticles is essential for numerous situations from the understanding of the flow of biological fluids t…
Flexible filaments buckle into helicoidal shapes in strong compressional flows
Brato Chakrabarti, Yanan Liu, John LaGrone +5
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 processe…
Morphological transitions of elastic filaments in shear flow
Yanan Liu, Brato Chakrabarti, David Saintillan +2
The morphological dynamics, instabilities and transitions of elastic filaments in viscous flows underlie a wealth of biophysical processes from flagellar propulsion to intracellula…
Deformation and shape of flexible, microscale helices in viscous flow
Jonathan T. Pham, Alexander Morozov, Alfred J. Crosby +2
We examine experimentally the deformation of flexible, microscale helical ribbons with nanoscale thickness subject to viscous flow in a microfluidic channel. Two aspects of flexibl…

Naïs Coq, Antoine Bricard, Francois-Damien Delapierre +4
We combine technical, experimental and theoretical efforts to investigate the collective dynamics of artificial microcilia in a viscous fluid. We take advantage of soft-lithography…
Buckled in translation
E. Wandersman, N. Quennouz, M. Fermigier +2
We report experiments on the deformation and transport of an elastic fiber in a viscous cellular flow, namely a lattice of counter-rotative vortices. We show that the fiber can buc…
