Traveling Strings of Active Dipolar Colloids Open
We study an intriguing new type of self-assembled active colloidal polymer system in 3D. It is obtained from a suspension of Janus particles in an electric field that induces parallel dipoles in the particles as well as self-propulsion in …

Dipolar colloids in three dimensions: non-equilibrium structure and re-entrant dynamics Open
Colloids provide a unique platform in which to explore the effect of activity upon well-controlled thermal many-body systems. Until now, experiments have been largely limited to 2d. This work describes the phase behaviour and dynamics of a…

Tuning higher order structure in colloidal fluids Open
We identify minimum energy clusters in dipolar colloids using confocal microscopy. In this thermal system, the population of clusters follows predictions from energy landscape calculations.

Identification and classification of clusters of dipolar colloids in an external field Open
Colloids can acquire a dipolar interaction in the presence of an external AC electric field. At high field strength, the particles form strings in the field direction. However, at weaker field strength, competition with isotropic interacti…

Tuning Higher Order Structure in Colloidal Fluids Open
Colloidal particles self assemble into a wide range of structures under external AC electric fields due to induced dipolar interactions [Yethiraj and Van Blaaderen Nature 421 513 (2003)]. As a result of these dipolar interactions, at low v…

Surface Tension Drives Cancer Cell Migration Open
A model used to explain the wetting of drops can also describe cell migration driven by variations in a surface's stiffness, a finding that could help in understanding how cancers grow.By
