  • Publication number: 20200407407
    Abstract: The present invention relates to an orally-administered gene carrier, and more specifically, to an orally-administered gene carrier having cationic protamine connected to an immunoglobulin Fc region by an SMCC linker, the cationic protamine enabling the condensation of an anionic gene. The orally-administered gene carrier enables protamine, which is a protein having cationic properties, to bind to an Fc region and be condensed with a gene having anionic properties, and thus may effectively induce the in vivo expression of the gene, and when orally administered, may enable the gene to be transferred to the small intestine by protecting the gene from a degradation reaction resulting from an immune action of white blood cells and stomach acid, and may enable the half-life of the gene to be relatively long when the gene is expressed in the small intestine, and thus a potential for a long-term treatment effect has been confirmed.

  • Publication number: 20200127354
    Abstract: A lithium ion conducting protective film produced using a layer-by-layer assembly process. The lithium ion conducting protective film is assembled on a substrate by a sequential exposure of the substrate to a first poly(ethylene oxide) (PEO) layer including a cross-linking silane component on the first side of the substrate, a graphene oxide (GO) layer on the first PEO layer, a second poly(ethylene oxide) (PEO) layer including a cross-linking silane component on the GO layer and a poly(acrylic acid) (PAA) layer on the second PEO layer. The film functions as a lithium ion conducting protective film that isolates the lithium anode from the positive electrochemistry of the cathode in a lithium-air battery, thereby preventing undesirable lithium dendrite growth.
