A Versatile Method for Synthesis of Light-Activated, Magnet-Steerable Organic–Inorganic Hybrid Active Colloids [PDF]

open access: yesMolecules, 2023
The immense potential of active colloids in practical applications and fundamental research calls for an efficient method to synthesize active colloids of high uniformity. Herein, a facile method is reported to synthesize uniform organic–inorganic hybrid

How to steer active colloids up a vertical wall [PDF]

open access: yesNature Communications
An important challenge in active matter lies in harnessing useful global work from entities that produce work locally, e.g., via self-propulsion. We investigate here the active matter version of a classical capillary rise effect, by considering a non ...

Interactions in active colloids [PDF]

open access: yesJournal of Physics: Condensed Matter, 2021
Abstract The past two decades have seen a remarkable progress in the development of synthetic colloidal agents which are capable of creating directed motion in an unbiased environment at the microscale. These self-propelling particles are often praised for their enormous potential to self-organize into dynamic nonequilibrium structures ...

Active colloidal molecules in activity gradients [PDF]

open access: yesPhysical Review E, 2022
We consider a rigid assembly of two active Brownian particles, forming an active colloidal dimer, in a gradient of activity. We show analytically that depending on the relative orientation of the two particles the active dimer accumulates in regions of either high or low activity, corresponding to, respectively, chemotaxis and antichemotaxis.

Designing active colloidal folders [PDF]

open access: yesThe Journal of Chemical Physics, 2022
Can active forces be exploited to drive the consistent collapse of an active polymer into a folded structure? In this paper, we introduce and perform numerical simulations of a simple model of active colloidal folders and show that a judicious inclusion of active forces into a stiff colloidal chain can generate designable and reconfigurable two ...

Self Organization of Binary Colloidal Mixtures via Diffusiophoresis

open access: yesFrontiers in Chemistry, 2022
Catalytic activity of the colloids and chemotactic response to gradients of the chemicals in the solution leads to effective interaction between catalytic colloids.

Osmotic pressure modulates single cell cycle dynamics inducing reversible growth arrest and reactivation of human metastatic cells

open access: yesScientific Reports, 2021
Biophysical cues such as osmotic pressure modulate proliferation and growth arrest of bacteria, yeast cells and seeds. In tissues, osmotic regulation takes place through blood and lymphatic capillaries and, at a single cell level, water and ...

Estimating the velocity of chemically-driven Janus colloids considering the anisotropic concentration field

open access: yesFrontiers in Chemistry, 2022
The application of the active colloids is strongly related to their self-propulsion velocity, which is controlled by the generated anisotropic concentration field.

Active colloids orbiting giant vesicles [PDF]

open access: yesSoft Matter, 2021
A self-propelled Janus colloid performs a persistent orbital motion around a giant unilamellar vesicle, even when the vesicle size is comparable to the particle size.
