Techniques for arranging materials on a substrate are provided. In one embodiment, a system may comprise a driver for providing a rotational force, an outer body having an inner surface, and an inner body having an outer surface and disposed within the outer body in a concentric relationship therewith. The inner body may be coupled to the driver to be rotated by the rotational force. The system may further comprise a coupler attached to the outer body in order to retain a substrate, which forms at least one patterned groove therein. A fluid channel, which may be defined between the inner and outer bodies, may be filled with a fluid medium containing materials such as nano materials. When the inner body rotates via the rotational force, the materials contained in the fluid medium may be arranged in the patterned groove of the substrate.
