Controlled assembly of single colloidal crystals using electro-osmotic micro-pumps
Ran Niu, Erdal C. Oğuz, Hannah Müller +4
We assemble charged colloidal spheres at deliberately chosen locations on a charged unstructured glass substrate utilizing ion exchange based electro-osmotic micro-pumps. Using mic…
Assembly and speed control in ion exchange based modular phoretic micro-swimmers
Ran Niu, Denis Botin, Julian Weber +2
We report an experimental study on ion-exchange based modular micro-swimmers in low-salt water. Cationic ion-exchange particles and passive cargo particles assemble into self-prope…
Microfluidic Pumping by Micromolar Salt Concentrations
Ran Niu, Patrick Kreissl, Aidan T. Brown +5
An ion-exchange-resin-based microfluidic pump is introduced that utilizes trace amounts of ions to generate fluid flows. We show experimentally that our pump operates in almost dei…
To make a glass - avoid the crystal
Thomas Palberg, Eckhard Bartsch, Richard Beyer +5
Colloidal model systems allow for a flexible tuning of particle sizes, particle spacings and mutual interactions at constant temperature. Colloidal suspensions typically crystalliz…
