University of Minnesota: Self-Assembling Solar Cells 

Sceintists at the University of Minnesota have created "a self-assembly technique that arranges microscopic electronic elements in their proper order thanks to the absolute enmity that exists between water and oil."

"By coating elements with a hydrophilic layer on one side and some hypdrophobic goo on the other, they've achieved the proper element orientation, and the final step in their work was the insertion of a pre-drilled, pre-soldered sheet, which picks up each element while being slowly drawn out of the liquid non-mixture."
