    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.

    Abstract: Methods for electrodeposition of conductive material on a conductive substrate that contains a pattern of a chemisorbed surfactant formed by a stamp having a patterned surface which is pressed onto the surface of the substrate for printing the substrate. Electrodeposition occurs by immersing the patterned substrate in a plating bath upon application of deposition potential or current to the conductive substrate. In embodiment, the chemisorbed surfactant on the surface of the substrate acts as a positive resist so that electrodeposition occurs on regions of the substrate not covered with surfactant. In another embodiment, electrodeposition occurs preferentially in regions of the substrate covered with the chemisorbed surfactant.

    Abstract: One aspect of the present invention relates to a method for transferring a patterned polyelectrolyte multilayer from a first surface, e.g., a PDMS stamp, to a second surface, e.g. fabric or a non-woven material, wherein the patterned polyelectrolyte multilayer on the first surface is brought into contact with the second surface in order to transfer the polyelectrolyte multilayer from the first surface to the second surface. Another aspect of the present invention relates to a stamp comprising a surface coated with a polyelectrolyte multilayer suitable for transfer to a substrate using the aforementioned method of transferring patterned multilayers.

    Abstract: Aliphatic dithiocarboxylic acid compositions (ADTCAs) that form self-assembled monolayers (SAMs) on metal surface such as gold surfaces are disclosed. These new SAMs were characterized by optical ellipsometry, contact angle goniometry, and polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS). The data indicates that the ADTCAs generate well packed and highly oriented monolayer films on gold surfaces. A method for using the ADTCAs in micro-contact printing is also disclosed, where ADTCA SAM protected regions are capable of more efficient cleaning under mild conditions due to instabilities in the ADTCA compositions.
