Orientational Dynamics of Fluctuating Dipolar Particles Assembled in a Mesoscopic Colloidal Ribbon
Helena Massana-Cid, Fernando Martinez-Pedrero, Andrejs Cebers +1
We combine experiments and theory to investigate the dynamics and orientational fluctuations of ferromagnetic microellipsoids that form a ribbon-like structure due to attractive di…
Bidirectional particle transport and size selective sorting of Brownian particles in a flashing spatially periodic energy landscape
Fernando Martinez-Pedrero, Helena Massana-Cid, Till Ziegler +3
We demonstrate a size sensitive experimental scheme which enables bidirectional transport and fractionation of paramagnetic colloids in a fluid medium. It is shown that two types o…
Orientational dynamics of colloidal ribbons self-assembled from microscopic magnetic ellipsoids
Fernando Martinez-Pedrero, Andrejs Cebers, Pietro Tierno
We combine experiments and theory to investigate the orientational dynamics of dipolar ellipsoids, which self-assemble into elongated ribbon-like structures due to the presence in…
Dipolar Rings of Microscopic Ellipsoids: Magnetic Manipulation and Cell Entrapment
Fernando Martinez-Pedrero, Andrejs Cebers, Pietro Tierno
We study the formation and dynamics of dipolar rings composed by microscopic ferromagnetic ellipsoids, which self-assemble in water by switching the direction of the applied field.…
Functional colloidal micro-sieves assembled and guided above a channel-free magnetic striped film
Fernando Martinez-Pedrero, Arthur V. Straube, Tom H. Johansen +1
Colloidal inclusions in lab-on-a-chip devices can be used to perform analytic operations in a non-invasive fashion. We demonstrate here a novel approach to realize fast and reversi…
Colloidal Microworms Propelling via a Cooperative Hydrodynamic Conveyor Belt
Fernando Martinez-Pedrero, Antonio Ortiz-Ambriz, Ignacio Pagonabarraga +1
We study propulsion arising from microscopic colloidal rotors dynamically assembled and driven in a viscous fluid upon application of an elliptically polarized rotating magnetic fi…
Magnetic Propulsion of Self-Assembled Colloidal Carpets: Efficient Cargo Transport via a Conveyor-Belt Effect
Fernando Martinez-Pedrero, Pietro Tierno
We demonstrate a general method to assemble and propel highly maneuverable colloidal carpets which can be steered via remote control in any direction of the plane. These colloidal…
