Emergent behavior in active colloids

A Zöttl, H Stark - Journal of Physics: Condensed Matter, 2016 - iopscience.iop.org
Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

Motility-induced phase separation

ME Cates, J Tailleur - Annu. Rev. Condens. Matter Phys., 2015 - annualreviews.org
