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…
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…
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…
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…
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…
Collective beating of artificial microcilia
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…
