METHOD FOR CONTROLLED ELECTROSTATIC ADHERENT DEPOSITION OF PARTICLES ON A SUBSTRATE

摘要

Provided is a method of fabricating a substrate having on a surface (110) thereof two or more spatially-resolved regions, each with a defined amount or concentration of one or more chemical components (120, 121, 122, 123), the method comprising: a) associating a chemical component with particles (120) of 1 micron to 500 microns diameter; and b) electrostatically depositing the particles on appropriate regions; and if a region is to receive a second chemical component (121), and repeating steps a) and b) for the chemical component.
