Swarms, which stem from collective behaviors among individual elements, are commonly
seen in nature. Since two decades ago, scientists have been attempting to understand the …

Unprecedented opportunities exist for the generation of advanced nanotechnologies based
on synthetic micro/nanomotors (MNMs), such as active transport of medical agents or the …

Active constituents burn fuel to sustain individual motion, giving rise to collective effects that
are not seen in systems at thermal equilibrium, such as phase separation with purely …

Achieving controlled mobility of microparticles in viscous fluids can become pivotal in
biologics, biotechniques, and biomedical applications. The self-assembly, trap**, and …

Mechanically programmable, reconfigurable micro/nanoscale materials that can dynamically
change their mechanical properties or behaviors, or morph into distinct assemblies or …

Light carries energy and momentum. It can therefore alter the motion of objects on the
atomic to astronomical scales. Being widely available, readily controllable, and broadly …

Emergent behavior in collectives of “robotic” units with limited capabilities that is robust and
programmable is a promising route to perform tasks on the micro and nanoscale that are …

Swarming, a phenomenon widely present in nature, is a hallmark of nonequilibrium living
systems that harness external energy into collective locomotion. The creation and study of …

The increasing accumulation of persistent nondegradable microplastics in the marine
environment represents a global environmental problem. Among emerging approaches to …

We study experimentally the effect of added salt in the phoretic motion of chemically driven
colloidal particles. We show that the response of passive colloids to a fixed active colloid, be …
