1. A method for depositing colloidal particles onto a substrate comprising:
- (a) providing a substrate having a surface;
(b) depositing a first layer of a first fluid onto the surface of the substrate;
(c) depositing a second layer of an aqueous dispersion of colloidal particles on top of the first layer of the first fluid;
(d) optionally covering the second layer with a cover so as to forming an assembly comprising a sandwich of the first and second layers between the substrate and the cover;
(e) removing the first layer of the first fluid; and
(f) removing the water from the second layer of the aqueous dispersion, leaving a layer of colloidal particles on the surface of the substrate

Abstract
A method for assembling colloidal particles onto a substrate surface through fluid transport. The method comprises placing a first fluid placed adjacent to the substrate surface, applying a colloidal dispersion on top of the first fluid layer and removal of the first fluid layer. The method is extremely versatile, and is especially useful in depositing colloidal materials in high aspect ratio channels and vias without the need for prior treatment of the surface.
