  • Publication number: 20190064066
    Abstract: The present disclosure relates to a fluorescent supramolecular biosensor, more particularly to a fluorescent supramolecular biosensor which shows change in fluorescence signal through binding to a specific bacterium and a method for preparing the same. The fluorescent supramolecular biosensor is advantageous in that it exhibits remarkably superior affinity and selectivity for a target bacterium. In addition, because a secondary coiled coil stereostructure is highly stabilized as the supramolecular building block is self-assembled to form the fluorescent supramolecular biosensor, the fluorescent supramolecular biosensor can be stored for a long period of time without structural change even at high temperatures.

  • Publication number: 20180293342
    Abstract: Disclosed is a method for simulating characteristics of a semiconductor device. An overlap matrix and a Hamiltonian representing atomic interaction energy information of a target semiconductor device are extracted by using a density functional theory (DFT), and Bloch states for corresponding energies are calculated based on the Hamiltonian, the overlap matrix, and energy-k relation within an effective energy region. A first reduced Hamiltonian and a first reduced overlap matrix having a reduced matrix size are obtained by applying the Hamiltonian and the overlap matrix to a transformation matrix that is obtained by orthonormalizing a matrix representing the Bloch states. A final transformation matrix and a final energy band structure where all unphysical branches, which are energy bands not corresponding to a first energy band structure in a second energy band structure, are removed within the effective energy region are calculated.

  • Patent number: 9822149
    Abstract: The present disclosure relates to a polypeptide having multiple directionality and a self-assembled nanostructure containing the same. Since R1 and R3 domains having ?-sheet structures are arranged to have antiparallel structures, it provides a more stabilized ?-helix structure than the existing polypeptide having single directionality. In addition, since the polypeptide of the present disclosure is prepared as an antiparallel pseudo-cyclic structure without additional structural element such as a linker, the associated synthesis process is simple and the molecular weight is relatively small. Since the polypeptide having multiple directionality having the structural and functional characteristics described above and a self-assembled nanostructure containing the same have excellent stability and transportability, they are applicable in various fields as drugs, for detection of substances in vivo, for targeting for drug delivery, and for inhibiting protein-mediated biomacromolecular interactions.
