Onsager reciprocal relations and chemo-mechanical coupling for chemically active colloids. [PDF]

open access: yesJournal of Chemical Physics, 2022
Similar to cells, bacteria, and other micro-organisms, synthetic chemically active colloids can harness the energy from their environment through a surface chemical reaction and use the energy to self-propel in fluidic environments.

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.

Guiding Self-Assembly of Active Colloids by Temporal Modulation of Activity. [PDF]

open access: yesPhysical Review Letters, 2022
Self-organization phenomena in ensembles of self-propelled particles open pathways to the synthesis of new dynamic states not accessible by traditional equilibrium processes. The challenge is to develop a set of principles that facilitate the control and

Active Colloids as Models, Materials, and Machines.

open access: yesAnnual Review of Chemical and Biomolecular Engineering, 2023
Active colloids use energy input at the particle level to propel persistent motion and direct dynamic assemblies. We consider three types of colloids animated by chemical reactions, time-varying magnetic fields, and electric currents.

Anomalous Cooling and Overcooling of Active Colloids. [PDF]

open access: yesPhysical Review Letters, 2021
The phenomenon that a system at a hot temperature cools faster than at a warm temperature, referred to as the Mpemba effect, has recently been realized for trapped 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.

Pair Interaction between Two Catalytically Active Colloids.

open access: yesSmall, 2023
Due to the intrinsically complex non-equilibrium behavior of the constituents of active matter systems, a comprehensive understanding of their collective properties is a challenge that requires systematic bottom-up characterization of the individual ...

Modeling Active Colloids: From Active Brownian Particles to Hydrodynamic and Chemical Fields

open access: yesAnnual Review of Condensed Matter Physics, 2022
Active colloids are self-propelled particles moving in viscous fluids by consuming fuel from their surroundings. Here, we review the numerical and theoretical modeling of active colloids propelled by self-generated near-surface flows.
