Photo 1
Sketch of a self-assembled bimodal superlattice of nanocrystals. The superlattice is composed of superparamagnetic iron oxide nanocrystals (blue) in a cubic array, with an icosohedron of 13 semiconducting lead selenide crystals (red) at the center of each cube. (The thirteenth lead selenide nanocrystal is at the center of the icosohedron.)

This electron microscopy image has been colorized to highlight the positions of the magentic iron oxide particles (blue) and the semiconducting lead selenide quantum dots (red).
