PACSim: A Flexible Simulation Framework for Polymer-Attenuated Coulombic Self-Assembly
Philipp Höllmer, Nicole Smina, John P. Marquardt +4
Polymer-Attenuated Coulombic Self-Assembly (PACS) is a flexible experimental approach for generating crystals from simple colloidal building blocks. The central components are char…
The free surface of a colloidal chiral fluid: waves and instabilities from odd stress and Hall viscosity
Vishal Soni, Ephraim Bililign, Sofia Magkiriadou +4
In simple fluids, such as water, invariance under parity and time-reversal symmetry imposes that the rotation of constituent 'atoms' are determined by the flow and that viscous str…
Targeted Assembly and Synchronization of Self-Spinning Microgears
Antoine Aubret, Mena Youssef, Stefano Sacanna +1
Self-assembly is the autonomous organization of components into patterns or structures: an essential ingredient of biology and a desired route to complex organization. At equilibri…
Unstable fronts and stable "critters" formed by microrollers
Michelle Driscoll, Blaise Delmotte, Mena Youssef +3
Condensation of objects into stable clusters occurs naturally in equilibrium and driven systems. It is commonly held that potential interactions, depletion forces, or sensing are t…
Trochoidal trajectories of self-propelled Janus particles in a diverging laser beam
Henrique Moyses, Jeremie Palacci, Stefano Sacanna +1
We describe colloidal Janus particles with metallic and dielectric faces that swim vigorously when illuminated by defocused optical tweezers without consuming any chemical fuel. Ra…
Artificial Rheotaxis
Jeremie Palacci, Stefano Sacanna, Anais Abrahmian +5
Motility is a basic feature of living microorganisms, and how it works is often determined by environmental cues. Recent efforts have focused on develop- ing artificial systems tha…
Light Activated Self-Propelled Colloids
J. Palacci, S. Sacanna, S. -H. Kim +3
Light-activated self-propelled colloids are synthesized and their active motion is studied using optical microscopy. We propose a versatile route using different photoactive materi…
Photoactivated Colloidal Dockers for Cargo Transportation
J. Palacci, S. Sacanna, A. Vatchinsky +2
We introduce a self-propelled colloidal hematite docker that can be steered to a small particle cargo many times its size, dock, transport the cargo to a remote location, and then…
Characterization of anisotropic nano-particles by using depolarized dynamic light scattering in the near field
Doriano Brogioli, Domenico Salerno, Valeria Cassina +4
Light scattering techniques are widely used in many fields of condensed and sof t matter physics. Usually these methods are based on the study of the scattered light in the far fie…
