Abstract: The present invention relates to a method for determining loss of gas in a gas container. According to an embodiment of the present invention, the method for determining the loss of gas in the gas container is characterized by including the steps of (a) filling a first container (10) with a component gas and a balance gas, (b) measuring a gas pressure inside the first gas container (11), (c) allowing the first gas container and a second gas container having an evacuated inside to communicate and performing a first-stage gas pressure split, and (d) measuring a gas pressure inside the second gas container, wherein an amount of the component gas adsorbed inside the gas container is calculated through a difference between a measured value of step (b) and a measured value of step (d) and is determined as an amount of gas loss.

Abstract: In order to quantitatively analyze nucleic acids present in a sample or a complex medium, a nucleic acid extraction or purification process is required. However, the yield of nucleic acid extraction and purification is greatly variable depending on the purification principle and the characteristics of kit and sample used. Hence, efficient normalization of nucleic acid extraction and purification yield is a prerequisite for accurate quantitative analysis of nucleic acid based on the original sample. The present invention relates to a quantitative analysis method of a nucleic acid present in a sample or a complex medium without amplification of a target nucleic acid.

Abstract: 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.
