    Abstract: The present invention provides a method for the selective placement of carbon nanotubes on a particular surface. In particular, the present invention provides a method in which self-assembled monolayers formed on an unpatterned or patterned metal oxide surface are used to attract or repel carbon nanotubes from a dispersion containing the same. In accordance with the present invention, the carbon nanotubes can be attracted to the self-assembled monolayers so as to be attached to the metal oxide surface, or they can be repelled by the self-assembled monolayers bonding to a predetermined surface other than the metal oxide surface containing the self-assembled monolayers.

    Abstract: An elastomeric stamp (10) is provided, which has a bulk surface (12) from which protruding features (14, 14') extend. A barrier layer (20) covers the bulk surface (12) and the protruding features (14, 14'). After applying an ink solution to the elastomeric stamp (10) and drying the elastomeric stamp (10), the elastomeric stamp (10) is brought into contact with a surface (42) of a first substrate (40). The surface (42) of the first substrate (40) has a high affinity with the ink molecules (32), which is utilized to effectively remove the ink molecules (32) from the contact surfaces (16, 16') of the protruding features (14, 14'). Subsequently, the elastomeric stamp (10) is brought into contact with the surface (52) of a second substrate (50). Ink molecules 32 are transferred from the edges (18, 18') of the protruding features (14, 14') to the surface (52) of a second substrate (50), thus forming an ink pattern in the form of a self­assembled monolayer on this surface (52). The patterning method of the present invention allows for the formation of high-definition ink patterns on a substrate (50) using a wide variety of inks.

    Abstract: An apparatus (95) and method for patterning a surface of an article (30), the apparatus (95) including a large-area stamp (50) for forming a self-assembled monolayer (36) (SAM) of a molecular species (38) on the surface (34) of a layer (32) of resist material, which is formed on the surface of the article (30). The large-area stamp (50) includes a layer (52) of an elastomer and has, embedded within it, mechanical structures (68, 80) which stiffen the large-area stamp (50) and deform it to control the stamped patterns. The method includes the steps of: forming a layer (32) of resist material is on the surface of the article (30), utilizing the large-area stamp (50) to form the SAM (36) on the surface (34) of the layer (32) of resist material, etching the layer (32) of resist material, and thereafter etching or plating the surface of the article (30).

    Abstract: A simple and reproducible preparative method for the fabrication of surface-chemical gradients is described herein. Surface-chemical gradient films are prepared by using a liquid front in relative motion to the substrate (e.g. immersion by a linear-motion drive or the use of a spreading droplet) to gradually expose substrate samples to very dilute solutions of adsorbates. As demonstrated by XPS, the self-assembled monolayer gradients produced in this way display a high packing density. This method can be used in the preparation of other gradients of various chemical or biochemical functionalities in one or two dimensions. Such gradients can be used in a wide variety of applications in such diverse areas as cell motility studies, nanotribology research, and high-throughput screening.
