Polymer materials provide solutions to some of the most pressing environmental,
manufacturing and health-care challenges. Traditional thermoplastic and thermoset …

Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

Biomolecular and physical cues of the extracellular matrix environment regulate collective
cell dynamics and tissue patterning. Nonetheless, how the viscoelastic properties of the …

We study the statistical properties of active Ornstein-Uhlenbeck particles (AOUPs). In this
simplest of models, the Gaussian white noise of overdamped Brownian colloids is replaced …

Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

The mechanical behaviour of cells is largely controlled by a structure that is fundamentally
out of thermodynamic equilibrium: a network of crosslinked filaments subjected to the action …

Cell migration is important in many biological processes, including embryonic development,
cancer metastasis and wound healing. In these tissues, a cell's motion is often strongly …

Active materials are characterized by continuous injection of energy at the microscopic level
and typically cannot be adequately described by equilibrium thermodynamics. Here we …

Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

We consider a Brownian particle which, in addition to being in contact with a thermal bath, is
driven by fluctuating forces which stem from active processes in the system, such as self …
