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

Dynamic overlap concentration scale of active colloids [PDF]
Physical Review E, 2021 By introducing the notion of a dynamic overlap concentration scale, we identify universal and previously unreported features of the mechanical properties of active colloids. These features are codified by recognizing that the characteristic length scale of an active particle's trajectory, the run-length, introduces a new concentration scale ...

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.

Directed assembly of active colloidal molecules
New Journal of Physics, 2019 Having a production line for microrobots is fundamental to their widespread application in many areas. Thanks to their flexibility, active colloidal molecules with dynamic function are a promising model for microrobots.
