Power-law intermittency in the gradient-induced self-propulsion of colloidal swimmers
Nick Oikonomeas-Koppasis, Stefania Ketzetzi, Daniela J. Kraft +1
Active colloidal microswimmers serve as archetypical active fluid systems, and as models for biological swimmers. Here, by studying in detail their velocity traces, we find robust…
Activity-induced microswimmer interactions and cooperation in one-dimensional environments
Stefania Ketzetzi, Melissa Rinaldin, Pim Dröge +2
Cooperative motion in biological microswimmers is crucial for their survival as it facilitates adhesion to surfaces, formation of hierarchical colonies, efficient motion, and enhan…
Height Distribution and Orientation of Colloidal Dumbbells Near a Wall
Ruben W. Verweij, Stefania Ketzetzi, Joost de Graaf +1
Geometric confinement strongly influences the behavior of microparticles in liquid environments. However, to date, nonspherical particle behaviors close to confining boundaries, ev…
Diffusion-based height analysis reveals robust microswimmer-wall separation
Stefania Ketzetzi, Joost de Graaf, Daniela J. Kraft
Microswimmers typically move near walls, which can strongly influence their motion. However, direct experimental measurements of swimmer-wall separation remain elusive to date. Her…
Slip length dependent propulsion speed of catalytic colloidal swimmers near walls
Stefania Ketzetzi, Joost de Graaf, Rachel P. Doherty +1
Catalytic colloidal swimmers that propel due to self-generated fluid flows exhibit strong affinity for surfaces. We here report experimental measurements of significantly different…
