Inferring interactions between active particles using harmonic traps
Arnaud Compagnie, Joscha Mecke, Ivo Buttinoni +1
Quantifying the interactions between active Janus particles remains a challenge that needs to be addressed to describe their collective behaviour. Inspired by a photonic force micr…
Active particles in tunable compressible environments
Venkata Manikantha Sai Ganesh Tanuku, Isha Malhotra, Lorenzo Caprini +3
Active particles affect their environment as much as the environment affects their active motion. Here, we present an experimental system where both can be simultaneously adjusted…
Drying of Soft Colloidal Films
Keumkyung Kuk, Julian Ringling, Kevin Gräff +7
Thin films made of deformable micro- and nano-units, such as biological membranes, polymer interfaces, and particle-laden liquid surfaces, exhibit a complex behavior during drying,…
Minimal numerical ingredients describe chemical microswimmers's 3D motion
Maximilian R. Bailey, C. Miguel Barriuso Gutiérrez, José Martín-Roca +6
The underlying mechanisms and physics of catalytic Janus microswimmers is highly complex, requiring details of the associated phoretic fields and the physiochemical properties of c…
Island Hopping of active colloids
Venkata Manikantha Sai Ganesh Tanuku, Peter Vogel, Thomas Palberg +1
Individual self-propelled colloidal particles, like active Brownian particles (ABP) or run-and-tumble swimmers (RT), exhibit characteristic and well-known motion patterns. However,…
Sedimentation and Levitation of Catalytic Active Colloids
Virginia Carrasco-Fadanelli, Ivo Buttinoni
Gravitational effects in colloidal suspensions can be easily turned off by matching the density of the solid microparticles with the one of the surrounding fluid. By studying the m…
