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

Physical 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.

The “isothermal” compressibility of active matter [PDF]
The 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 ...

Active matter therapeutics. [PDF]
Nano 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.

A colloidal viewpoint on the sausage catastrophe and the finite sphere packing problem
Nature Communications, 2023 It is commonly believed that the most efficient way to pack a finite number of equal-sized spheres is by arranging them tightly in a cluster. However, mathematicians have conjectured that a linear arrangement may actually result in the densest packing ...

The European Physical Journal E, 2013 The study of systems with sustained energy uptake and dissipation at the scale of the constituent particles is an area of central interest in nonequilibrium statistical physics. Identifying such systems as a distinct category -- Active Matter -- unifies our understanding of autonomous collective move- ment in the living world and in some surprising ...

Control cell migration by engineering integrin ligand assembly
Nature Communications, 2022 Engineering peptide assembly that controls integrin ligand presentation on the molecular level possesses by far the highest ligand density, expanding the perspective of ligand-density-dependent modulation.

Cage Length Controls the Nonmonotonic Dynamics of Active Glassy Matter [PDF]
, 2021 Dense active matter is gaining widespread interest due to its remarkable similarity with conventional glass-forming materials. However, active matter is inherently out of equilibrium and even simple models such as active Brownian particles (ABPs) and ...
