Magnetophoretic long jump of magnetic microparticles in an engineered magnetic stray field landscape for highly localized and large throughput on-chip fractionation
Rico Huhnstock, Lukas Paetzold, Piotr Kuswik +1
A common issue faced by magnetic particle-based Lab-on-a-chip systems, e.g, for medical diagnostics, is the intrinsic fabrication-related polydispersity in particle sizes and magne…
Topological sorting of magnetic colloidal bipeds
Aneena Rinu Perayil, Piotr KuÅwik, 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…
Topologically cloaked magnetic colloidal transport
Anna M. E. B. Rossi, Thomas Märker, Nex C. X. Stuhlmüller +8
Cloaking is a method of making obstacles undetectable. Here we cloak unit cells of a magnetic pattern squeezed into an otherwise periodic pattern from a magnetically driven colloid…
Magnetic colloidal single particles and dumbbells on a tilted washboard moire pattern in a precessing external field
Farzaneh Farrokhzad, Nex C. X. Stuhlmüller, Piotr KuÅwik +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 ex…
