Scientists have revealed some of the remarkable properties of small colonies of tiny magnetic particles.
The tiny particles are able to self-assemble in to microscopic machines that can manipulate other particles. It is hoped that this could pave the way for new fabrication processes that aren't possible with conventional machines.
The asters can swim around, open wide like Pac-Man and hug another object, transporting it to another spot. Watch the video below, wherein one aster curls up and transports a small glass bead across the field of view, with gracefully organic movement. The glass bead weighed four times that of the self-assembled aster, according to an ANL news release.
