| 20090246285 | MONODISPERSED ORGANIC MONOLAYER COATED CALCIUM-CONTAINING NANOPARTICLES - A method for the synthesis of monodispersed, organic-monolayer coated, calcium-containing nanoparticles is presented. A biphasic liquid system comprises an aqueous phase of bare particles and an organic phase containing organic molecules with carboxylic acid end group is mixed. The carboxylic acid group binds to the surface of the calcium-containing particles and the particles are coated with a monolayer of organic molecules. The exposed surface of the coated particles is more hydrophobic than the surface of the bare particle and the particles are extracted to the organic phase. The process changes the geometry of the particles and decreases the size distribution in a population of particles. | 10-01-2009 |
| 20090246527 | NANOPARTICLES HAVING SUB-NANOMETER FEATURES - An article has a surface, at least a portion of which has a local radius of curvature of about 1000 nm or less. For example, the article may be a nanoparticle or a surface, a portion of which has a roughness characterized by a radius of curvature of about 1000 nm or less. A monolayer coating disposed on the surface includes a plurality of ligands organized into ordered domains having a characteristic size of less than or about equal to 10 nm. | 10-01-2009 |
| 20100036156 | MONOLAYER-COATED SURFACES AS CATALYTIC PLATFORMS FOR ORGANIC REACTIONS - This invention provides a method for increasing the activity of catalysts. The method requires the introduction of the catalyst into nano-structured surfaces. The catalysts are introduced as functional groups in molecules forming a monolayer on a surface. A mixed monolayer of catalyst and inert molecules generates ordered domains of molecules on the surface. The catalyst is confined in regions of 0.5 nm to 3 nm in size and is surrounded by an inert material. The presence of such ordered domains that commensurate in size with the reactants, enhance the performance of the catalyst and increase the rate of the reaction. | 02-11-2010 |
| 20100086604 | ABSORBANT SUPERHYDROPHOBIC MATERIALS, AND METHODS OF PREPARATION AND USE THEREOF - The present invention relates to coated, absorbent, freestanding assemblies comprising inorganic nanowires, articles of manufacture comprising the same, processes of producing the same and methods of use thereof. The assemblies of this invention are useful in various applications, including removal of organics or hydrophobic materials, and waterproofing applications. | 04-08-2010 |
| 20100105796 | LIQUID SUPRAMOLECULAR NANOSTAMPING (LISUNS) - The present invention is directed to methods and materials for producing complements and reproductions of a master, including such preparation in a high throughput setting, using, inter-alia, liquid supramolecular nanostamping (LiSuNS). | 04-29-2010 |
| 20100248159 | PATTERNING VIA OPTICAL-SATURABLE TRANSISIONS - An optical material system for nanopatterning is provided that includes one or more material systems having spectrally selective reversible and irreversible transitions by saturating one of the spectrally selective reversible transitions with an optical node retaining a single molecule in a configuration and exposing the single molecule to its spectrally irreversible transitions to form a pattern. | 09-30-2010 |
| 20100273679 | METHODS FOR THE PREPARATION OF DNA MICROARRAYS WITH LINEAR HIGH DENSITY PROBES - A method for the realisation of DNA microarrays with linear high density probes, comprising a phase of replication of template DNA strands of a template microarray and a subsequent phase of stamping of the molecules obtained by replication on a substrate via the SuNS technique; the template strands ( | 10-28-2010 |
| 20110056845 | INSULATED NANOGAP DEVICES AND METHODS OF USE THEREOF - The present invention provides a method to eliminate undesired parallel conductive paths of nanogap devices for aqueous sensing. The method involves the electrical insulation of an electrode pair, except for the nanogap region wherein electrical response is measured. The magnitude of undesired ionic current in a measurement is reduced by two orders of magnitude. The process to accomplish the present invention is self-aligned and avoids fabrication complexity. The invention has a great potential in nanogap device applications. | 03-10-2011 |
| 20110160094 | NANOCONTACT PRINTING - A method of stamping of molecular patterns and/or devices based on the reversible self-assembly of molecules, particularly organic molecules is disclosed. This method is suitable for the stamping of almost any nanofabricated device and can be used to transferring a large amount of pattern information from one substrate to another at the same time. | 06-30-2011 |
