Abstract:
A method of manufacturing a gas sensor includes using a metal ligand and carbon nanotubes (“CNTs”). The method includes forming electrodes on a substrate, coating a paste, in which the metal ligand including a metal having adsorption selectivity with respect to at least one specific gas and carbon nanotubes (“CNTs”) are mixed, on the substrate on which the electrodes are formed, and reducing the metal ligand in the paste.
Abstract:
An electrodialysis apparatus includes a sample chamber including first and second dialysis membranes and filled with a sample between the first dialysis membrane and the second dialysis membrane, an anode chamber including an anode and filled with a first chamber solution between the anode and the first dialysis membrane, and a cathode chamber including a cathode and filled with a second chamber solution between the cathode and the second dialysis membrane. In particular, when a voltage is applied to the anode and the cathode, ionic materials of the sample move to the anode and cathode chambers.
Abstract:
A micro-fluid reaction vessel includes an upper plate formed of an elastomer, a lower plate adhered to the upper plate, a micro-chamber and a micro-channel formed on an inner surface of the upper plate facing the lower plate and an inlet hole and an outlet hole formed in the upper plate and through which a fluid flows into or out of, respectively. The micro-channel is constructed to be closed by pressure applied to the upper plate and elastically restored when the pressure is not applied. A micro fluid reaction method uses the micro fluid reaction vessel and a method of manufacturing forms the microfluid reaction vessel.
Abstract:
Disclosed herein is a method for detecting DNA using a nanopore including treating the surface of a nanopore formed in a solid substrate with a substance carrying positive charges; introducing a DNA-containing sample into the surface-treated nanopore; and detecting electrical signals generated during translocation of the sample through the nanopore. Also disclosed herein is device for detecting DNA using a nanopore including a solid substrate including a nanopore, treated with a substance which carries positive charges to change a surface property of the nanopore so that the nanopore surface carries positive charges; an electrode applying voltage to the nanopore of the solid substrate; and a measurement unit measuring an electrical signal generated during translocation of a DNA-containing sample through the nanopore.
Abstract:
The present invention relates to a high strength polyethylene-2,6-naphthalate fiber produced by a method comprising controlling the stress-strain curve and fine structure of an undrawn yarn such that the drawability of the undrawn yarn in a drawing step is improved. The industrial polyethylene-2,6-naphthalate fiber with high strength according to the present invention shows high strength and low shrinkage, and a treated cord formed from this fiber has improved dimensional stability and high strength, such that it can be advantageously employed as a fibrous reinforcement material of rubber products such as tires.
Abstract:
A substrate for immobilizing a physiological material is provided. The substrate comprises a substrate material; a primer layer formed on the substrate material; and an immobilization layer formed on the primer layer. The primer layer is capable of enhancing the attachment between the substrate and the immobilization layer. The substrate for immobilizing a physiological material can provide the immobilization layer with a stable, uniform, and high density through a simple process.
Abstract:
Provided is a linker functional group patterning method for biomolecule immobilization. The patterning method includes preparing a coating composition including a hydrophobic group-containing silane compound and a hydrophilic group-containing silane compound; forming a surface tension control layer by coating the coating composition on a substrate for biomoleucle immobilization; and forming a linker functional group pattern on the surface tension control layer using a coating composition including a linker functional group-containing compound followed by thermal treatment. The linker functional group pattern is formed in a uniform size and distribution and contains high-density linker functional groups.
Abstract:
A microarray including hydrogel and a plurality of probes which are immobilized in discrete regions of the hydrogel, and a method of preparing the same are provided. When using the microarray and method, a solid substrate is not required and many biomolecules can be immobilized in a small volume, thereby obtaining high sensitivity. Since gel can be cut to obtain many pieces, many microarrays can be prepared at once.

The optical detection device includes a light source for generating excitation light to excite a sample, a detection plate having an optical waveguide with the sample mounted thereon, a linear symmetry lens for shaping the excitation light into a desired shape having a uniform intensity distribution and transmitting it to the detection plate, and a detector for detecting radiation from the sample.
Abstract:
A wafer transfer apparatus can transfer wafers to and from at least one process chamber quickly and in a small amount of space. The wafer transfer includes an arm unit, and a multi-blade connected to said arm unit so as to be rotatable relative to the arm unit. The multi-blade has at least two wafer supports configured to respectively support wafers as all lying in a horizontal plane. The arm unit includes a first arm mounted for rotation in a horizontal plane, and a second arm carried by the first arm and rotatable relative to the first arm in a horizontal plane. The multi-blade is carried by the second arm.
