Journal ArticleDOI
Dynamical clustering and phase separation in suspensions of self-propelled colloidal particles.
Ivo Buttinoni,Ivo Buttinoni,Julian Bialké,Felix Kümmel,Felix Kümmel,Hartmut Löwen,Clemens Bechinger,Clemens Bechinger,Thomas Speck +8 more
TL;DR: A (quasi-)two-dimensional colloidal suspension of self-propelled spherical particles propelled due to diffusiophoresis in a near-critical water-lutidine mixture finds that the driving stabilizes small clusters and undergoes a phase separation into large clusters and a dilute gas phase.
Journal ArticleDOI
Microswimmers in patterned environments
TL;DR: A novel species of microswimmers whose active motion is due to the local demixing of a critical binary liquid mixture and can be easily tuned by illumination is developed, which can be employed to develop advanced sorting, classification and dialysis techniques.
Journal ArticleDOI
Circular motion of asymmetric self-propelling particles.
Felix Kümmel,Borge ten Hagen,Raphael Wittkowski,Ivo Buttinoni,Ralf Eichhorn,Giovanni Volpe,Hartmut Löwen,Clemens Bechinger +7 more
TL;DR: This work produces asymmetric microswimmers by soft lithography and studies their circular motion on a substrate and near channel boundaries in full agreement with a theory of Brownian dynamics for asymmetric self-propelled particles.
Journal ArticleDOI
Microswimmers in Patterned Environments
TL;DR: In this paper, the authors demonstrate with experiments and simulations how microscopic self-propelled particles navigate through environments presenting complex spatial features, which mimic the conditions inside cells, living organisms and future lab-on-a-chip devices.
Journal ArticleDOI
Programmable colloidal molecules from sequential capillarity-assisted particle assembly.
TL;DR: The full programmability of the capillarity-assisted particle assembly approach opens up new directions not only for assembling and studying complex materials with single-particle-level control but also for fabricating new microscale devices for sensing, patterning, and delivery applications.
