  • Cloaking is a technique for rendering obstacles undetectable, previously applied to waves and now extended to particles. Here using a time-periodic magnetic field, authors report that paramagnetic colloidal particles are guided around cloaked regions in a deformed magnetic lattice, resuming motion as if the distortion were nonexistent.

  • External fields can control the motion of colloidal particles inducing different trajectories depending on for instance the particle size. The authors here use nonperiodic energy landscapes and topological protection to transport a collection of identical colloidal particles simultaneously and independently.

  • Topological growth control can produce colloidal rods with specific, adjustable lengths. Using an external magnetic field and metamorphic patterns, authors assemble paramagnetic colloidal spheres into walking bipeds, whose length determines their movement towards or away from an active zone.
