We developed a novel self-assembly process to fabricate an orderly array of particle wires constructed from a close-packed structure from colloidal solution without preparation of patterned templates. A substrate was immersed into the solution containing particles perpendicular to the liquid surface and the liquid surface was moved downward by evaporation of solution. Particles formed a mono/multi-particle layer and the particle layer was cut by the periodic drop-off of the solution. This process allowed us to fabricate the orderly array of particle wires and to show the high ability of the self-assembly process for fabrication of nano/micro-structures constructed from nano/micro particles or blocks.
