  • Patent number: 11000590
    Abstract: The present disclosure relates to a composition for transduction of a virus in a cell by using a crosslinked product of PEGylated magnetic nanoparticles and catechol grafted poly-L-lysine by application of an external magnetic field. When the composition is used, a virus may be delivered into cells more rapidly and efficiently than in intracellular uptake of a virus by CAR-mediated endocytosis.
    Type: Grant

  • Patent number: 8369536
    Abstract: An apparatus for reproducing sound from original source signals has a control device, a first speaker, and a second speaker. The control device receives first and second original source signals, and controls magnitudes and phases of the received first and second original source signals so that a sound pressure level in a pre-determined zone is higher than a sound pressure level in a zone other than the pre-determined zone, and outputs first and second controlled source signals. The first speaker receives the first controlled source signal and reproduces sound. The second speaker receives the second controlled source signal and reproduces sound. The apparatus according provides a sound environment in which only the person using the sound system enjoys the sound.
