The biosensing apparatus includes: a chamber having an inlet through which a fluid containing a biomaterial enters and an outlet through which the fluid exits; and a plurality of biosensors inserted and fixed in the chamber. Each biosensor includes: a support unit having a fluid channel through which a fluid containing a biomaterial flows; and a sensing unit disposed on the support unit in such a way that the sensing unit is exposed three-dimensionally in the fluid channel of the support unit, the sensing unit being surface-treated with a reactive material that is to react with the biomaterial flowing through the fluid channel. | 01-21-2010 |
20100015718 | SUBSTRATE FOR ANALYZING COVERAGE OF SELF-ASSEMBLED MOLECULES AND ANALYZING METHOD USING THE SAME - Provided are a substrate for analyzing the coverage of self-assembled molecules and a method for analyzing the coverage of the self-assembled molecules in nanowire and nanochannel patterned on solid surface, solid surface, or bulk solid surface by using the nanoparticles. According to the method, the presence of specific functional groups of self-assembled molecules and the degree of reaction can be analyzed by introducing nanoparticles to a biomaterial immobilization substrate including self-assembled molecules and measuring the number of gold nanoparticles existing on the surface. The substrate for analyzing the coverage of self-assembled molecules includes: a biomaterial immobilization substrate; a self-assembled molecular layer formed on the substrate and having a functional group capable of reacting with an amine group; a capture DNA molecule having an amine group bounded to the self-assembled molecular layer; and a probe DNA molecule bound to the capture DNA molecule and having nanoparticles attached to on the surface. | 01-21-2010 |
20100050866 | NANOWIRE FILTER, METHOD FOR MANUFACTURING THE SAME, METHOD FOR REMOVING MATERIAL ABSORBED THEREON, AND FILTERING APPARATUS HAVING THE SAME - There are provided a nanowire filter, a method for manufacturing the same, a filtering apparatus having the same, and a method for removing material adsorbed on the nanowire filter. The filtering apparatus includes: a filter having a supporting member and a plurality of nanowires supported on the supporting member and arranged in a crystallized state; and a body into which the filter is inserted and secured, and which has an inlet for guiding an introduced fluid to the filter and an outlet for discharging the fluid filtered through the filter to the outside. | 03-04-2010 |
20100080932 | METHOD FOR SELECTIVELY FUNCTIONALIZING NON-MODIFIED SOLID SURFACE AND METHOD FOR IMMOBILIZING ACTIVE MATERIAL ON THE FUNCTIONALIZED SOLID SURFACE - Provided is a method for selectively functionalizing unmodified solid surface, not oxidized and nitrified, into an aldehyde group, and a method for immobilizing an active material such as bio material or functional material on the functionalized aldehyde solid surface through strong and stable chemical bonding. Differently from a conventional method immobilizing deoxyribonucleic acid (DNA) using a cross linker, the method of the present invention does not require a cross linker reaction step to thereby shorten a process. Also, since a cross linker is absent, the monomolecular layer on the surface of a device is thin, which reduces a perturbation effect by molecular layer. This is useful in fabrication of molecular electronic devices and bio-active devices. In addition, since the bio material or functional material is selectively immobilized only on the unmodified surface, the present invention can functionalize only a specific solid surface and develop a highly sensitive sensor and an improved functional device. | 04-01-2010 |
20100090254 | BIOSENSOR AND MANUFACTURING METHOD THEREOF - Provided is a biosensor which can detect a specific biomaterial by an interaction between target molecules and probe molecules, and a manufacturing method thereof. The biosensor includes: a first conductive semiconductor substrate; a second conductive doping layer formed on the semiconductor substrate; an electrode formed on top of both opposite ends of the doping layer; and probe molecules immobilized on the doping layer. | 04-15-2010 |
20100119733 | METHOD OF IMMOBILIZING ACTIVE MATERIAL ON SURFACE OF SUBSTRATE - Provided is a method of immobilizing an active material on a surface of a substrate. The method including cleaning a substrate, functionalizing a surface of the substrate using a hydroxyl group, functionalizing the surface of the substrate at atmospheric pressure using a vaporized organic silane compound, and immobilizing an active material to an end of the surface of the substrate. Therefore, since evacuation or the use of carrier gas is not necessary, a uniform, high-density, single-molecular, silane compound film can be formed inexpensively, simply, and reproducibly, and an active material can be immobilized to the single-molecular silane compound film. | 05-13-2010 |
20110017613 | GAS STORAGE MEDIUM, GAS STORAGE APPARATUS AND METHOD THEREOF - Provided are gas storage medium, a gas storage apparatus having the same and a method thereof. The gas storage medium includes a plurality of material layers each having a variable valence, wherein each of the material layers includes redundant electrons that are not participated in chemical bonding. | 01-27-2011 |
