20080206877 | Reactors for selective enhancement reactions and methods of using such reactors - Micro-reactors for selective enhancement of ligands by exponential enrichment (ISOS) include a reactant chamber defined in a fluoropolymer. A target exposure aperture controls a surface area, crystal face or orientation and surface features of a target that is exposed to a random mixture of candidate molecules. The surface area of the target can be selected based on number or concentration of candidate species to enhance candidate competition. The target surface can be formed by deposition of a thin film of a target material on a rigid substrate such as a glass plate. Selected exposure areas are typically substantially smaller than a characteristic cross sectional area of a reactant chamber volume and can be at least as small as 0.1 mm | 08-28-2008 |

20090155573 | SCAFFOLD-ORGANIZED METAL, ALLOY, SEMICONDUCTOR AND/OR MAGNETIC CLUSTERS AND ELECTRONIC DEVICES MADE USING SUCH CLUSTERS - A method for forming arrays of metal, alloy, semiconductor or magnetic clusters is described. The method comprises placing a scaffold on a substrate, the scaffold comprising molecules selected from the group consisting of polynucleotides, polypeptides, and perhaps combinations thereof. Polypeptides capable of forming α helices are currently preferred for forming scaffolds. Arrays are then formed by contacting the scaffold with plural, monodispersed ligand-stabilized clusters. Each cluster, prior to contacting the scaffold, includes plural exchangeable ligands bonded thereto. If the clusters are metal clusters, then the metal preferably is selected from the group consisting of Ag, Au, Pt, Pd and mixtures thereof. A currently preferred metal is gold, and a currently preferred metal cluster is Au | 06-18-2009 |
