摘要： The present application provides a verification method and system of a sample introduction device dedicated to gas chromatography for precisely measuring a concentration of atmospheric greenhouse gas. The verification method of a sample introduction device dedicated to gas chromatography for precisely measuring a concentration of atmospheric greenhouse gas includes the steps of: 1) calculating, by a bias size calculation unit, a degree of bias in a tedlar bag using a correlation between a bias of Pbag to Pcyl and a bias of xbag to xcyl; and 2) determining, by a device performance determination unit, a device having the smallest value of a size of the bias calculated from the bias size calculation unit as an optimal device.

摘要： Provided is a method of preparing Raman-active nanoparticles, which includes a) preparing a metal nanocore having a nano-star shape from a first reaction solution in which a first metal precursor is mixed with a buffer solution; b) fixing a Raman reporter in the metal nanocore; and c) forming a metal shell, which surrounds the nanocore in which the Raman reporter is fixed, from a second reaction solution in which a second metal precursor is mixed with the nanocore in which the Raman reporter is fixed. The Raman reporter has a binding affinity for each of a first metal of the metal nanocore and a second metal of the metal shell.

摘要： The present invention relates to a culture vessel for three-dimensional cell cultivation and a three-dimensional cell co-cultivation method using the same. The culture vessel comprises a well formed by a column positioned thereon and at least one support protruding from the column within the well. In contrast to conventional techniques, the present invention allows cells to be cultured at a position spaced from a culture vessel, thus enjoying the advantage of smoothly supplying oxygen necessary for three-dimensional cell culture structures.

摘要： The present invention relates to a nano-dynamic biosensor and a fabrication method therefor. A biosensor according to the present invention comprises a substrate having a hollow structure and a graphene layer formed thereon wherein a probe material is bound to the surface of the graphene layer and the resonance vibration of the hollow structure formed in the substrate is modulated as the probe material increases in weight when a target material to be detected is coupled to the probe material without being labeled, whereby the biosensor is expected to take advantage of the modulation to measure the coupling of the target material including vaccinia virus with high sensitivity on a femtogram (10−15 g) level.

摘要： The present invention relates to particle measuring apparatus and a particle measuring method, whereby particle counts per size range can be measured with a high accuracy using a laser power scanning in which lasers of several powers are sequentially irradiated. First, minimum powered lasers capable of measuring particles having more than relevant size are irradiated to a particle measurement space for a predetermined time in response to plural counts of each mutually different particle size, and the counts of particles per size are measured by detecting a scattered light. Furthermore, the counts of particles belonging to each size range can be accurately calculated through an algorithm using the actually measured value.
