摘要： Methods and apparatus are described for patterned deposition of nanostructure-containing materials by self-assembly and related articles. According to an exemplary embodiment self-assembly method for depositing nanostructure-containing materials includes forming a nanostructure-containing material. The nanostructure-containing material is chemically functionalized and dispersed in a liquid medium to form a suspension. At least a portion of a substrate having a surface that can attract the functionalized nanostructure-containing material is brought into contact with the suspension. The substrate is separated from the suspension. The nanostructure-containing material adheres to the portion of the substrate when separated from the suspension. According to another exemplary embodiment, hydrophilic and hydrophobic regions are formed on the surface of the substrate before bringing the substrate into contact with the suspension. The functionalized nanostructure-containing material is hydrophilic and adheres to the hydrophilic region of the substrate when separated from the suspension.

摘要： A method for depositing a nanostructure-containing material onto an object or substrate includes one or more of the following: forming a solution or suspension of nanostructure-containing material (420); selectively adding 'chargers' to the solution (420); immersing electrodes (410, 430) in the solution (420), the substrate or object upon which the nanostructure material is to be deposited acting as one of the electrodes (430); applying a direct and/or alternating current electrical field between the two electrodes (410, 430) for a certain period of time, thereby causing the nanostructure materials in the solution (420) to migrate toward and attach themselves to the substrate electrode (450); and subsequent optional processing of the coated substrate. Associated objects and devices are also provided. A method for separating nanostructures based on their properties and/or geometry is also described.
