November 1, 2012

These are electron microscope images of "colloidal atoms," micrometer-sized particles with patches that allow bonding only along particular directions. From left to right: particle with one patch (analogous to a hydrogen atom), two, three, four (analogous to a carbon atom), five, six, and seven patches. Credit: Image courtesy of Vinothan N.
