Light, Matter, Action: Shining Light on Active Matter. [PDF]

open access: yesACS Photonics, 2023
Light carries energy and momentum. It can therefore alter the motion of objects from atomic to astronomical scales. Being widely available, readily controllable and broadly biocompatible, light is also an ideal tool to propel microscopic particles, drive them out of thermodynamic equilibrium and make them active.

Active matter therapeutics. [PDF]

open access: yesNano Today, 2020
Nanotherapies based on micelles, liposomes, polymersomes, nanocapsules, magnetic nanoparticles, and noble metal nanoparticles have been at the forefront of drug delivery in the past few decades. Some of these nanopharmaceuticals have been commercially applied to treat a wide range of diseases, from dry eye syndrome to cancer.

Playing with active matter

open access: yesAmerican Journal of Physics, 2023
In the past 20 years, active matter has been a very successful research field, bridging the fundamental physics of nonequilibrium thermodynamics with applications in robotics, biology, and medicine. Active particles, contrary to Brownian particles, can harness energy to generate complex motions and emerging behaviors. Most active-matter experiments are

Pulsating Active Matter

open access: yesPhysical Review Letters, 2023
We reveal that the mechanical pulsation of locally synchronised particles is a generic route to propagate deformation waves. We consider a model of dense repulsive particles whose activity drives periodic change in size of each individual. The dynamics is inspired by biological tissues where cells consume fuel to sustain active deformation.

Active Matter, Microreversibility, and Thermodynamics. [PDF]

open access: yesResearch (Wash D C), 2020
Active matter, comprising many active agents interacting and moving in fluids or more complex environments, is a commonly occurring state of matter in biological and physical systems. By its very nature, active matter systems exist in nonequilibrium states.

Towards a thermodynamics of active matter [PDF]

open access: hybridPhysical Review E, 2015
Self-propulsion allows living systems to display unusual collective behavior. Unlike passive systems in thermal equilibrium, active matter systems are not constrained by conventional thermodynamic laws. A question arises however as to what extent, if any, can concepts from classical thermodynamics be applied to nonequilibrium systems like active matter.

Active matter invasion [PDF]

open access: yesSoft Matter, 2019
Biological materials such as bacterial biofilms and eukaryotic cells combine their intrinsic activity with growth dynamics to create distinct patterns of motion for invading confined spaces.

Chiral active matter

open access: yesEurophysics Letters, 2022
Abstract Chiral active matter comprises particles which can self-propel and self-rotate. Examples range from sperm cells and bacteria near walls to autophoretic L-shaped colloids. In this perspective article we focus on recent developments in chiral active matter.

The “isothermal” compressibility of active matter [PDF]

open access: yesThe Journal of Chemical Physics, 2021
We demonstrate that the mechanically defined “isothermal” compressibility behaves as a thermodynamic-like response function for suspensions of active Brownian particles. The compressibility computed from the active pressure—a combination of the collision and unique swim pressures—is capable of predicting the critical point for motility induced phase ...
