Active colloids, capable of autonomous motion by harnessing energy available in their surroundings, are of significance for advancing micro/nanoscale technologies. Light, as a ubiquitous external stimulus to propel the motion of colloid particles, offers unique benefits such as remote controllability, flexible tunability, and high temporal and spatial ...

Chemical Auxiliary for Photocatalytic Active Colloids
Journal of the American Chemical SocietyActive colloids with the ability to self-propel and collectively organize are emerging as indispensable elements in microrobotics and soft matter physics. For chemically powered colloids, their activity is often induced by gradients of chemical species in the particle's vicinity.

Magnetically Powered Active Colloids
Active colloids can be powered by external magnetic fields when they contain or are made of magnetic material. The general strategy to achieve propulsion is based on the application of uniform, time-dependent magnetic fields which induce periodic displacements or deformations, rectified into a net translation.openaire +1 more source
