Machine-learned topological transport of magnetic colloids
Sebastian Wohlrab, Aneena Rinu Perayil, Piotr Kuświk +6
By modulating the orientation of a uniform magnetic field it is possible to transport magnetic microparticles above magnetic patterns. In periodic patterns, driving control loops t…
Tracking the Brownian motion of DNA-functionalized magnetic nanoparticles for conformation analysis beyond the optical resolution limit
Christian Janzen, Fabian Schmid-Michels, Yahya Shubbak +6
Brownian motion provides access to hydrodynamic properties of nanoscale objects independent of their optical resolvability. Here, we present a diffusion-based approach to infer eff…
Topological sorting of magnetic colloidal bipeds
Aneena Rinu Perayil, Piotr Kuświk, Maciej Urbaniak +5
Topologically nontrivial adiabatic loops of the orientation of a homogeneous external magnetic field drive the walking of paramagnetic colloidal bipeds above a deformed quasi-perio…
Magnetic colloidal single particles and dumbbells on a tilted washboard moire pattern in a precessing external field
Farzaneh Farrokhzad, Nex C. X. Stuhlmüller, Piotr Kuświk +6
We measure the dynamical behavior of colloidal singlets and dumbbells on an inclined magnetic moiré pattern, subject to a precessing external homogeneous magnetic field. At low ext…
Topologically controlled synthesis of active colloidal bipeds
Jonas Elschner, Farzaneh Farrokhzad, Piotr Kuświk +6
Topological growth control allows to produce a narrow distribution of outgrown colloidal rods with defined and adjustable length. We use an external magnetic field to assemble para…
Simultaneous and independent topological control of identical microparticles in non-periodic energy landscapes
N. C. X. Stuhlmüller, F. Farrokhzad, P. Kuświk +6
Topological protection ensures stability of information and particle transport against perturbations. We explore experimentally and computationally the topologically protected tran…
