Colloids go exotic Physicists in the Netherlands have created artificial crystals made of colloidal particles that could be used to explore the behaviour of ordinary ionic crystals. The team discovered a number of new crystal structures with the system, which could also be useful for applications such as "electronic-ink" (Nature 437 235).
Scientists routinely use colloid suspensions to model solids and liquids, such as the way they melt and freeze.
