Abstract

Chiral colloidal clusters To advance the use of colloids as building blocks for the fabrication of large-scale complex structures for applications in nanotechnology, it is desirable to give them the functionality and variability found in chemistry. A step in that direction has now been achieved with the development of magnetic colloids that can rapidly self-assemble into a variety of isomeric forms. Depending on the shape of the colloidal blocks relative to their spontaneous direction of magnetization, these colloids self-assemble into structures with controlled helicity. If the size ratio between the colloidal spheres in the assembly is large enough, a single helicity is chosen, right or left. This work opens up a new link between colloidal science and chemistry that could lead to the assembly of a wide variety of nanoparticles and mesopolymers.
