  • Publication number: 20200225221
    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.

  • Publication number: 20120227467
    Abstract: The present invention relates to a device for testing resist pressure of a vessel wherein gas is stored at a high compressed state, before the use of the vessel, and to a method for testing resist pressure of a vessel by using the testing device. The device includes: the vessel provided as an object to which a resist pressure test is carried out; an elastic tube placed in the interior of the vessel and adapted to fill a liquid into the interior thereof; a pressurizing means adapted to apply a predetermined pressure to the elastic tube to allow the elastic tube to be expanded; and a pressure gauge adapted to gauge the pressure in the interior of the vessel, wherein a gas is filled into the vessel to apply a predetermined pressure to the interior of the vessel by the expansion of the elastic tube.
