Dynamic Assembly of Active Colloids: Theory and Simulation [PDF]
Advanced Theory and Simulations, 2020 Because they consume energy to drive their motion, systems of active colloids are intrinsically out of equilibrium. In past decades, a variety of intriguing dynamic patterns have been observed in systems of active colloids, which offer a new platform for

Colloidal transport by active filaments [PDF]
The Journal of Chemical Physics, 2017 Enhanced colloidal transport beyond the limit imposed by diffusion is usually achieved through external fields. Here, we demonstrate the ballistic transport of a colloidal sphere using internal sources of energy provided by an attached active filament.

Activity-controlled annealing of colloidal monolayers [PDF]
Nature Communications, 2019 AbstractMolecular motors are essential to the living, generating fluctuations that boost transport and assist assembly. Active colloids, that consume energy to move, hold similar potential for man-made materials controlled by forces generated from within. Yet, their use as a powerhouse in materials science lacks.

Electric and Magnetic Field-Driven Dynamic Structuring for Smart Functional Devices
Micromachines, 2023 The field of soft matter is rapidly growing and pushing the limits of conventional materials science and engineering. Soft matter refers to materials that are easily deformed by thermal fluctuations and external forces, allowing for better adaptation and

Active colloidal chains with cilia- and flagella-like motion
New Journal of Physics, 2018 It has been shown that self-assembled chains of active colloidal particles can present sustained oscillations. These oscillations are possible because the effective diffusiophoretic forces that mediate the interactions of colloids do not respect the ...

Anomalous Dynamics of Colloids and Their Cluster Formation in Active Liquids [PDF]
EPJ Web of ConferencesWe examine the dynamics of individual colloidal particles in active media. Unlike Brownian particles, which display a Gaussian distribution in displacement, the colloids in active media show deviations from this form.

Tuning the Random Walk of Active Colloids: From Individual Run-and-Tumble to Dynamic Clustering. [PDF]
Physical Review Letters, 2019 Active particles such as swimming bacteria or self-propelled colloids spontaneously self-organize into large-scale dynamic structures. The emergence of these collective states from the motility pattern of the individual particles, typically a random walk,
