Physics of Fiberboids — •Igor Kulic — CNRS, Institut Charles Sadron, 23 rue du Loess BP 84047, 67034 STRASBOURG Cedex 2

Fiberboids are filaments trapped at the interface between two phases, able of harnessing energy and matter fluxes across the interface to produce a rolling-like self-propulsion. We experimentally demonstrate several common driving mechanisms and develop the physical framework for understanding the complex active dynamics of fiberboids. The phenomenon is highly generic and plays a role across scales, from the macroscopic realm down to the nanoscale, where it gives rise to chemical fuel-driven surface motility of various filamentous viruses.
