  • Publication number: 20250082787
    Abstract: The present invention provides an alginic acid-based injectable hydrogel system for labeling an accurate position of a disease lesion and effectively delivering a drug to a target region. The formulation of the present invention can make it easy to locally inject a contrast agent and a drug into a target region while controlling the release rate of the contrast agent or the drug, with the formation of the hydrogel in the injected region. Through the advantages, the labeled position can be accurately determined from images, thereby enhancing the precision of surgical operation, with a minimal incision formed therefor. In addition, when used, the alginic acid-based injectable hydrogel system allows the effective local delivery of a drug to a target region while increasing the long-acting effect of the drug.

  • Patent number: 9449986
    Abstract: A memory device includes a cell region including a channel region extending to be perpendicular to an upper surface of a substrate, a plurality of gate electrode layers stacked on the substrate adjacently to the channel region, a peripheral circuit region including a first active region disposed in the vicinity of the cell region, a second active region having an area larger than an area of the first active region, a plurality of first contacts connected to the first active region, and a plurality of second contacts connected to the second active region. A distance between the plurality of first contacts is less than that between the plurality of second contacts.
