| NSL, in the words of a professional |

| "The idea behind nanosphere lithography is that polystyrene (a kind of plastic) nanospheres are put into a water solution and dropped onto a flat piece of glass. The spheres tend to pack in a single layer in a pattern right next to each other. The water is evaporated off so you just have the polystyrene spheres on glass. Then you put that into a vacuum chamber and evaporate a material like silver or gold (or whatever) onto the mask. That material goes through the holes of the mask and lands on the glass. Then you can remove the mask (dunk the whole thing in a solvent like acetone that dissolves the polystyrene but nothing else). That leaves behind only the material that you just deposited in a pattern that is determined by the holes of the mask." -Ms. Traci Jensen |
