title: Collective behaviour of self-propelled catalytic micromotors.
abstract: Biology widely employs catalytic reactions to power biomotors and cells. These dynamic entities can self-organize into swarms or self-assemble into functional micro- or nanostructures. Synthetic micro-/nanojet engines and nanomotors, driven by catalytic reactions, can move with high power and perform multiple tasks. Collective behavior of these microengines has recently been observed which includes swarming activities and the formation of multiconstituent entities. This feature article discusses recent developments, presents new discoveries on collective motion of self-propelled microjet engines and suggests next steps to undertake in the field of collective micromachines.
