Diffusion, phase behavior and gelation in a two-dimensional layer of colloids in osmotic equilibrium with a polymer reservoir
Sam E Griffiths, Nick Koumakis, Aidan T Brown +3
The addition of enough non-adsorbing polymer to an otherwise stable colloidal suspension gives rise to a variety of phase behavior and kinetic arrest due to the depletion attractio…

Dynamic optical rectification and delivery of active particles
Nick Koumakis, Aidan T. Brown, Jochen Arlt +3
We use moving light patterns to control the motion of {\it Escherichia coli} bacteria whose motility is photo-activated. Varying the pattern speed controls the magnitude and direct…
