Exploring and exploiting faceted colloids and their self assembly

FIG. 1. Hollow cubes are made (left) by growing cubic hematite cubes, coating it with a 100-nm silica shell, and then etching out the hematite core (scale bar = 1 micrometer). Movie (above) shows Brownian motion of cubes in an optical microscope. [Quicktime required]
