Field‐Driven Active Colloids as Distributed Micromachines: Bridging Physics, Control, and Function Across Length Scales
ABSTRACT Field‐driven active colloids offer a route to microscale machines whose behavior can be programmed by external electric and magnetic fields. At the micron scale, thermal fluctuations, hydrodynamic interactions, interparticle forces, and field‐mediated actuation combine to connect active matter physics with con...
