Particle sizing for flowing colloidal suspensions using flow-differential dynamic microscopy
James A Richards, Vincent A Martinez, Jochen Arlt
Particle size is a key variable in understanding the behaviour of the particulate products that underpin much of our modern lives. Typically obtained from suspensions at rest, meas…
Dynamics-dependent density distribution in active suspensions
Jochen Arlt, Vincent A Martinez, Angela Dawson +2
Self-propelled colloids constitute an important class of intrinsically non-equilibrium matter. Typically, such a particle moves ballistically at short times, but eventually changes…
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…
Escherichia coli as a model active colloid: a practical introduction
Jana Schwarz-Linek, Jochen Arlt, Alys Jepson +6
The flagellated bacterium Escherichia coli is increasingly used experimentally as a self-propelled swimmer. To obtain meaningful, quantitative results that are comparable between d…
