Colloidal spheres coaxed to self-assemble into photonic crystals

It is difficult to make colloidal spheres self-assemble into photonic crystals, which are valued for their optical properties. A team of engineers and scientists report they have found a pathway toward the self-assembly of these elusive photonic crystal structures never assembled before on the sub-micrometer scale.
