Abstract:
1. A method of forming a planar assembly of particles in a designated area on a substrate, said method comprising: providing a first electrode positioned in a first plane, and a second electrode positioned in a second plane different from the first plane, an electrolyte solution located therebetween and a plurality of particles therein, wherein the second electrode comprises a planar electrode having a surface and an interior, the surface or interior having been modified to produce spatial modulations in properties of the second electrode; and generating an electric field at the interface between the electrolyte solution and the second electrode to form a planar assembly of substantially one layer of particles in a designated area on the second electrode, wherein the designated area is defined by the spatial modulations in properties of the second electrode and the properties of the second electrode are those affecting the local distribution of the electric field at said interface.
