While manipulating the AFM tip across a plane, the ink is transported onto the substrate through a water meniscus. The ink molecules, or atoms, jump from the tip to the substrate because of a strong polar bond.

| The method is actually pretty simple. It works just like a printer, moving back and forth over a surface. Only the AFM tip would write on the x and y axes of a coordinate plane. Literally, the tip would graph what is programmed to be written. While manipulating the AFM tip across a plane, the ink is transported onto the substrate through a water meniscus. The ink molecules, or atoms, jump from the tip to the substrate because of a strong polar bond. |
