Keywords: colloid, styrene, self-assembly

Thanks to a new assembly strategy, colloidal particles can now be coaxed into sophisticated structures much in the same way that atoms combine to form molecules (Nature, DOI: 10.1038/nature11564). The development could lead to novel functional materials such as a diamond lattice made from colloidal-sized particles with specific optical properties.

Whether it’s in organic molecules or atomic lattices, atoms’ predictable ways of arranging themselves via valency give . . .
