The simultaneous positioning of multiple colloidal particles using optical tweezers is described here. It is illustrated that novel structures of very specific design can be constructed on a microscopic scale (see Figure) and that the structure can be locked in by photopolymerization of the surrounding solvent. Such artificially created surfaces may find applications as lithographic masks or diffraction gratings.
