Abstract: The present invention relates to cell membrane-derived nanovesicles, a method of preparing the same, and a pharmaceutical composition and a diagnostic kit using the nanovesicles. The cell membrane-derived nanovesicles according to the present invention may prevent the occurrence of potential side effects because intracellular materials (e.g., genetic materials and cytosolic proteins) unnecessary for delivery of therapeutic or diagnostic substances are removed from the nanovesicles. In addition, since the nanovesicles may be targeted to the specific types of cells or tissues, therapeutic or diagnostic substances may be predominantly delivered to the targeted cells or tissues while delivery of therapeutic or diagnostic substances to untargeted sites may be inhibited. Therefore, when the cell membrane-derived nanovesicles are applied to disease treatment, the side effects of therapeutic substances such as drugs may be reduced, so that suffering and inconvenience of patients may be alleviated during the course of treating diseases, and therapeutic efficacy may be improved. In addition, the cell membrane-derived nanovesicles of the present invention, in which substances for the treatment or diagnosis of diseases are loaded, and a method of preparing the nanovesicles may be used in vitro or in vivo for therapeutic or diagnostic purposes, or for experimental use.

Abstract: Disclosed are a superhydrophilic surface body, a fabricating method thereof, and a filter for oil and water separation, including a superhydrophilic surface. The method for fabricating a superhydrophilic surface body includes a first step of forming a polyaniline nanofiber layer on a surface of a base material, a second step of changing the polyaniline nanofiber layer into a completely oxidized pernigraniline base state, a third step of forming a self-assembled monomolecular film having a polymer polymerization initiation functional group on a surface of the polyaniline nanofiber layer, and a fourth step of forming a silica layer on a surface of the self-assembled monomolecular film. In the third step, the polyaniline nanofiber layer is reduced to a leucoemeraldine state.

Abstract: Provided are a method for manufacturing a perovskite nanocrystal particle light-emitter where an organic ligand is substituted, a light-emitter manufactured thereby, and a light emitting device using the same. A method for manufacturing an organic-inorganic-hybrid perovskite nanocrystal particle light-emitter where an organic ligand is substituted may comprise the steps of: preparing a solution including an organic-inorganic-hybrid perovskite nanocrystal particle light-emitter, wherein the organic-inorganic-hybrid perovskite nanocrystal particle light-emitter comprises an organic-inorganic-hybrid perovskite nanocrystal structure and a plurality of first organic ligands surrounding the organic-inorganic-hybrid perovskite nanocrystal structure; and adding, to the solution, a second organic ligand which is shorter than the first organic ligands or includes a phenyl group or a fluorine group, thereby substitutes the first organic ligands with the second organic ligand. Thus, since energy transfer or charge injection into the nanocrystal structure increases through ligand substitution, it is possible to further increase light emitting efficiency and increase durability and stability by means of a hydrophobic ligand.
