Shape-dependent direction reversal in anisotropic catalytic microswimmers
Solenn Riedel, Mengshi Wei, Daniela J. Kraft
The propulsion direction of active particles is a key feature in self-propelled systems and depends on the propulsion mechanism and environmental conditions. Here, using 3D micro-p…
Autonomous life-like behavior emerging in active and flexible microstructures
Mengshi Wei, Daniela J. Kraft
Many organisms leverage an interplay between shape and activity to generate motion and adapt to their environment. Embedding such feedback into synthetic microrobots could eliminat…
Colloidal Pivots Enable Brownian Metamaterials and Machines
Julio Melio, Martin van Hecke, Silke E. Henkes +1
Biological machines harness targeted deformations that can be actuated by Brownian fluctuations. However, while synthetic micromachines can similarly leverage targeted deformations…
Fabrication and characterization of bimetallic silica-based and 3D-printed active colloidal cubes
Silvana A. Caipa Cure, Daniela J. Kraft
Simulations on self-propelling active cubes reveal interesting behaviors at both the individual and the collective level, emphasizing the importance of developing experimental anal…
