Continuous manipulation and characterization of colloidal beads and liposomes via diffusiophoresis in single- and double-junction microchannels
Adnan Chakra, Naval Singh, Goran T. Vladisavljević +4
We reveal an unreported physical mechanism that enables the pre-concentration, sorting and characterization of charged polystyrene nanobeads and liposomes dispersed in a continuous…
Purely viscous acoustic propulsion of bimetallic rods
Jeffrey McNeill, Nathan Sinai, Justin Wang +4
Synthetic microswimmers offer models for cell motility and their tunability makes them promising candidates for biomedical applications. Here we measure the acoustic propulsion of…
Direct Measurement of Unsteady Microscale Stokes Flow Using Optically Driven Microspheres
Nicolas Bruot, Pietro Cicuta, Hermes Bloomfield-Gadelha +4
A growing body of work on the dynamics of eukaryotic flagella has noted that their oscillation frequencies are sufficiently high that the viscous penetration depth of unsteady Stok…
Reversible Trapping of Colloids in Microgrooved Channels via Diffusiophoresis under Steady-State Solute Gradients
Naval Singh, Goran T. Vladisavljević, François Nadal +3
The controlled transport of colloids in dead-end structures is a key capability that can enable a wide range of applications, such as bio-chemical analysis, drug delivery and under…
Acoustic propulsion of a small bottom-heavy sphere
Francois Nadal, Sebastien Michelin
We present here a comprehensive derivation for the speed of a small bottom-heavy sphere forced by a transverse acoustic field and thereby establish how density inhomogeneities may…
Model of collective fish behavior with hydrodynamic interactions
Audrey Filella, François Nadal, Clément Sire +2
Fish schooling is often modeled with self-propelled particles subject to phenomenological behavioral rules. Although fish are known to sense and exploit flow features, these models…
Clustering instability of focused swimmers
Eric Lauga, Francois Nadal
One of the hallmarks of active matter is its rich nonlinear dynamics and instabilities. Recent numerical simulations of phototactic algae showed that a thin jet of swimmers, obtain…
Asymmetric steady streaming as a mechanism for acoustic propulsion of rigid bodies
Francois Nadal, Eric Lauga
Recent experiments showed that standing acoustic waves could be exploited to induce self-propulsion of rigid metallic particles in the direction perpendicular to the acoustic wave.…
