Controlling the Reactivity of Adsorbed DNA on Template Surfaces
Langmuir, 2008The ability to place DNA on surfaces with increased and controllable reactivity is of fundamental importance in the development of next-generation DNA and protein biochips. The present work demonstrates the ability to control both the localization of the DNA on a surface and its reactivity by a self-assembly approach that is dependent on two variables:

Patterned surface as a template for DNA-based nanotechnology
The 2003 Congress on Evolutionary Computation, 2003. CEC '03., 2004A novel method of DNA patterning on silicon surface based on atomic force microscopy (AFM) is presented. This method is based on the AFM anodic oxidation technique, which has the ability to make nano-level oxide patterns on the silicon surface.

Steering On-Surface Polymerization with Metal-Directed Template
Journal of the American Chemical Society, 2013On-surface polymerization represents a novel bottom-up approach for producing macromolecular structures. To date, however, most of the structures formed using this method exhibit a broad size distribution and are disorderly adsorbed on the surface. Here we demonstrate a strategy of using metal-directed template to control the on-surface polymerization ...

Enantioselectivity in Random Deposition Processeses on Template Surfaces
The Journal of Physical Chemistry B, 2008A molecular model is proposed to study the enantioselective adsorption of chiral species on metallic surfaces modified through the preadsorption of another chiral species, known as template surfaces. It is found that anisotropic and exclusive interactions among adsorbed species are essential factors in the enantioselective process.

Surface-Templated Formation of Protein Microfibril Arrays
Langmuir, 2008Ordered arrays of collagen microfibrils form rapidly and spontaneously from a solution of monomers deposited onto a mica substrate. These arrays are well-ordered and apparently continuous over the entire substrate. Correlated atomic force microscope images and Laué diffraction patterns indicate that the protein alignment and microfibril formation is ...

Surface chemistry of carbon-templated mesoporous aluminas
Physical Chemistry Chemical Physics, 2009Using infrared spectroscopy, a comparative investigation was carried out of the surface properties of mesoporous aluminas prepared by the carbon templating route and of a commercial alumina PURAL SB. In the hydroxylated state the mesoporous materials bear surface OH groups terminally bonded to an octahedral Al3+ ion, which has basic properties.

Templating Surfaces with Gradient Assemblies
The Journal of Adhesion, 2005One of the most versatile and widely used methods of forming surfaces with position-dependent wettability is that conceived by Chaudhury and Whitesides more than a decade ago [Science 256, 1539 (1992)]. In this paper we review several projects that utilize this gradient-forming methodology for: controlled of deposition of self-assembled monolayers on ...

The Packing of a Template on a Flat Surface
Journal of Mechanical Design, 1980Two ways of nesting are covered: (1) all templates in uniform orientation, and (2) alternate columns of inverted templates. Columns of templates are formed and neighboring columns are meshed together. Then the template is rotated to a new orientation. The optimum packing is obtained by searching through the tightest packing of individual orientations ...

Quasicrystal surfaces: structure and potential as templates
Journal of Physics: Condensed Matter, 2002We present a review of recent progress in determining the surface structure of quasicrystals, with emphasis on their connections to mathematical tiling models. The review focusses in particular on the five-fold surface of icosahedral Al-Pd-Mn and the ten-fold surface of decagonal Al-Ni-Co.

A template for calculating rock surface roughness
Earth Surface Processes and Landforms, 1997This software (which accompanies McCarroll and Nesje, 1996, Earth Surface Processes and Landforms Vol. 21, 963–977) is designed to quantify the roughness of rock surfaces from profiles recorded using either a micro-roughness meter or a simple profile gauge.
