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…
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…
