| 20090155800 | BIOSENSOR HAVING NANO WIRE AND MANUFACTURING METHOD THEREOF - There is provided a biosensor capable of increasing a detecting sensitivity of a target substance by using a nano wire having excellent electrical characteristics and by immobilizing a receptor of the target substance to be detected on a substrate which is disposed between a nano wire and another nano wire and a method for manufacturing the same. A biosensor according to the present invention can be manufactured with an arrangement in which the nano wire is selectively arranged on a solid substrate in a matrix and, therefore, many materials can be detected at the same time. Particularly, since the degradation of electrical characteristics of the nano wire can be prevented in the present invention, a target substance is very sensitively detected through a small amount thereof. | 06-18-2009 |
| 20090155816 | BIOSENSOR HAVING NANO WIRE FOR DETECTING FOOD ADDITIVE MONO SODIUM GLUTAMATE AND MANUFACTURING METHOD THEREOF - There is provided a biosensor capable of increasing a detecting sensitivity of a target substance of glutamate, by using a nano wire having excellent electrical characteristics and by immobilizing a receptor of glutamate to be detected on a substrate which is disposed between a nano wire and another nano wire and a method for manufacturing the same. The biosensor for detecting glutamate according to the present invention can be manufactured with an arrangement in which the nano wire is selectively arranged on a solid substrate in a matrix. Since this biosensor can prevent the degradation of the nano wire in the electrical characteristic, it can sensitively detect glutamate even through a small amount thereof is contained in a food so that it can be effectively used in detecting the food additive existing in the processed foodstuffs. | 06-18-2009 |

| 20100119710 | Patterning apparatus and method using dip-pen nanolithography - An apparatus and a method according to example embodiments is capable of patterning ink on a substrate by using dip-pen nanolithography regardless of the interaction between the ink and the substrate. The patterning apparatus may includes a heat supply control device. The heat supply control device may supply heat so as to liquefy the ink and facilitate the patterning of the ink on the substrate. The melting point of the ink may be set within the predetermined temperature controlled by the heat supply control device. | 05-13-2010 |
| 20100270265 | METHOD FOR ADSORPTION OF NANO-STRUCTURE AND ADSORPTION MATTER USING SOLID THIN FILM MASK - A method of adsorbing a nano-structure and an adsorption material using a solid thin film mask, including; depositing the mask over the entire surface of a tip of a probe microscope, grinding the end of the tip having the mask against a solid, thus removing the mask from the end of the tip, depositing a linker molecule layer over the entire surface of the tip the end of which has no mask, immersing the tip having the deposited linker molecule layer in a nano-structure solution, thus adsorbing the nano-structure on the linker molecule, and removing the mask from the tip. The mask is used to prevent deformation of the tip, and the nano-structure and the adsorption material can be deposited only on the end of the tip, regardless of the properties of the nano-structure and the adsorption material and regardless of the surface material of the tip and the properties thereof. | 10-28-2010 |
| 20110059544 | OLFACTORY RECEPTOR-FUNCTIONALIZED TRANSISTORS FOR HIGHLY SELECTIVE BIOELECTRONIC NOSE AND BIOSENSOR USING THE SAME - In accordance with an aspect of the present invention, there is provided a transistor including: a substrate; a source electrode and a drain electrode formed being spaced apart from each other on the substrate; a nanostructure electrically contacted with and formed between the source electrode and the drain electrode; and a lipid membrane having an olfactory receptor protein which is formed to cover surfaces of the source electrode, the drain electrode, and the nanostructure.
