A substrate (1) for spatially selective micro and nanometer scale deposition and / or reaction, said substrate comprising a support (3), a conductive layer (5) on said support, a static A dielectric layer (7) for holding a charge pattern, for example, a photoconductive layer of a material that disperses an electrostatic charge when incident light is received thereon, and a chemical functional layer (9). A substrate characterized in that it is formed in a predetermined manner and affects the movement of charged droplets in the emulsion (15) on the substrate. The chemically functional layer provides a surface for chemical functionalization of the substrate or prevents access or reaction to the dielectric or photoconductive layer. |
