Scientists are using light beams to build and reshape microscopic crystals
Researchers have developed a method using laser beams to assemble and rearrange microscopic particles into complex crystal structures, acting as invisible tweezers that can build materials from the bottom up.
Researchers at institutions like the University of Michigan are using highly focused laser beams to manipulate colloidal particles into intricate patterns. These light beams exert tiny forces that can push, pull, and lock microscopic bits of matter into place. By adjusting the intensity and path of the light, scientists can actually reshape these crystals in real-time.
