Abstract

A method for electrode-based patterning of thin film, self-assembled nanoparticles. The method uses a variety of types of thin films and electrodes.

Claims

1. A method for patterning thin films, the method comprising the steps of:

providing an electrode supported on a substrate;

providing a fluid permeable thin film adjacent to the electrode;

applying a potential to the electrode in an amount sufficient to cause separation of the thin film from the adjacent electrode.

2. The method of claim 1, wherein the electrode is a platinum electrode.

3. The method of claim 1, wherein the thin film is water soluble.

4. The method of claim 1, wherein the thin film is a grown film.

5. The method of claim 1, wherein the thin film is a spun-on film.

6. The method of claim 1, wherein the thin film is planar.

7. The method of claim 1, wherein the thin film comprises stacked nanoparticles.

8. The method of claim 1, wherein the thin film is a self-assembled film.

9. The method of claim 8, wherein the self-assembled film includes nanoparticles.

10. The method of claim 1, wherein the thin film is flexed prior to separation.

11. The method of claim 10, wherein the thin film is flexed via an electro-osmotic force.

12. The method of claim 1, wherein the thin film is an electrophoretically deposited, self-assembled film.
