  • Patent number: 7931866
    Abstract: The methods and apparatus disclosed herein concern nanoparticle layers uniformly distributed on a surface or substrate. In certain embodiments of the invention, the nanoparticle layers are of use for Raman spectroscopy. In certain embodiments of the invention, a micelle-metal ion complex is formed and deposited on a surface. The polymer component of the micelle-metal ion complex may be removed resulting in formation of nanoparticles of a uniform size and distribution. The polymers may contain one or more ligands. The number and type of ligands in a micelle will determine the type and amount of metal ion bound to the micelle, in turn determining the metal composition and size of the nanoparticles. The distribution micelle-metal ion complexes on a surface may determine the distribution and periodicity of the nanoparticle layer. In other embodiments, rod or columnar-shaped nanoparticles may be generated. Other embodiments concern the generation of uniform alloy nanoparticles.

  • Patent number: 7494815
    Abstract: The present invention provides a method and apparatus for analyzing compounds with amino group(s) contained in biological organisms. In this method, a compound with amino group(s) is derivatized and then the derivative of the compound with amino group(s) is eluted by liquid chromatography using a stepwise elution means on a concentration gradient. Subsequently, the derivative of the compound with amino group(s) eluted from the liquid chromatography is detected by mass spectrometry.

  • Publication number: 20080261202
    Abstract: Polyfunctional reagents are disclosed that are capable of reversibly binding to target substances, for example nucleic acid, proteins, polypeptides, cells, cell components, microorganisms or viruses, for use in purifying or otherwise manipulating them. The reagents comprise a tagging group for manipulating and/or detecting the target substance when bound to the polyfunctional reagent. The polyfunctional reagents work by binding the target substance at a first pH and then releasing it at a second pH, usually higher than the first. Examples of tagging groups include tagging group members of a specific binding pair which is capable of binding to a specific binding partner and/or a label.

  • Publication number: 20080227092
    Abstract: The invention relates to methods of manipulating immobilised carbohydrates by derivatisation. Depending on the nature of the derivatisation, the carbohydrate may thereby be more easily detected and/or identified or handled. In particular, the invention relates to methods of preparing a reactive sugar comprising the steps of: i) providing a sample comprising a reducing sugar; ii) providing a solid support covalently attached to a linker comprising a capture group comprising an —NH2 group, wherein said linker optionally is attached to said solid support via a spacer; iii) reacting said reducing sugar with said —NH2 group, thereby obtaining an immobilised sugar; iv) reacting free —NH2 groups with a capping agent, wherein the capping agent comprises a reactive group capable of reacting with an —NH2 group; and v) reducing C?N bonds with a reducing agent, thereby obtaining an reactive sugar of the structure SugarCHn—NH— linked to a solid support via a linker and optionally a spacer, wherein n is 1 or 2.

  • Publication number: 20080193983
    Abstract: The present invention is directed to the synthesis of molecules guided b connector polynucleotides (CPNs capable of hybridizing to complementary connector polynucleotides (CCPNs) harbouring at least one functional entity comprising at least one reactive group. At least one of said CCPNs capable of hybridize to at least two CPNs. Each CPN will “call” for one or more CCPNs capable of hybridization to the CPN. Following the formation of a supramolecular hybridization complex comprising a plurality of CPNs and a plurality of CCPNs, the reaction of functional entity reactive groups result I the formation of a molecule comprising covalently linked functional entities. The formation of the molecule involves the transfer of functional entities from one or more “donor CCPNs” to at least on “acceptor CCPN” with which the transferred functional entities were not associated prior to the transfer.
