Autonomously Probing Viscoelasticity in Disordered Suspensions
Clara Abaurrea-Velasco, Celia Lozano, Clemens Bechinger +1
Recent experiments show a strong rotational-diffusion enhancement for self-propelled microrheological probes in colloidal glasses. Here, we provide microscopic understanding using…
Propagating Density Spikes in Light-Powered Motility-Ratchets
Celia Lozano, Benno Liebchen, Borge ten Hagen +2
Combining experiments and computer simulations, we use a spatially periodic and flashing light-field to direct the motion of phototactic active colloids. Here, the colloids self-or…
Colloidal Brazil nut effect in microswimmer mixtures induced by motility contrast
Soudeh Jahanshahi, Celia Lozano, Borge ten Hagen +2
We numerically and experimentally study the segregation dynamics in a binary mixture of microswimmers which move on a two-dimensional substrate in a static periodic triangular-like…
Tuning the motility and directionality of self-propelled colloids
Juan Ruben Gomez-Solano, Sela Samin, Celia Lozano +3
Microorganisms are able to overcome the thermal randomness of their surroundings by harvesting energy to navigate in viscous fluid environments. In a similar manner, synthetic coll…
