Tunable dynamics of flexible magnetic microcrosses: synchronous rotation, breathing and out-of-plane arm overtaking
Joseph Tavacoli, Andris P. Stikuts, Mihir Dass +2
We combine colloidal self-assembly and soft-lithography techniques to realize flexible magnetic microcrosses that can be manipulated via external, time dependent magnetic fields. T…
Engineering tunable fractional Shapiro steps in colloidal transport
Andris P. Stikuts, Seemant Mishra, Artem Ryabov +2
Shapiro steps are quantized plateaus in the velocity-force or velocity-torque curve of a driven system, when its speed remains constant despite an increase in the driving force. Fo…
Curvature induces and enhances transport of spinning colloids through narrow channels
Eric Cereceda-López, Marco De Corato, Ignacio Pagonabarraga +3
The effect of curvature and how it induces and enhances the transport of colloidal particles driven through narrow channels represent an unexplored research avenue. Here we combine…
Controlling Colloidal Flow through a Microfluidic Y-junction
Alexander P. Antonov, Matthew Terkel, Fabian Jan Schwarzendahl +3
Microscopic particles flowing through narrow channels may accumulate near bifurcation points provoking flow reduction, clogging and ultimately chip breakage. Here we show that the…
