Abstract: The present invention relates to a method for producing dextran polymer-based amplified nucleic acid aptamer nanoconstructs which efficiently and selectively capture a specific target molecule, the method comprising linking a short nucleic acid sequence or a complementary sequence for formation of nanoconstructs and a nucleic acid aptamer sequence for capture of the specific target molecule to a dextran polymer by a chemical reaction, mixing the resulting polymer/nucleic acid substances with each other to form nanostructures, subjecting the nanostructures to rolling circle amplification, thereby forming a nucleic acid aptamer having a repeated structure. The dextran polymer-based amplified nucleic acid aptamer nanoconstructs have the effect of efficiently and selectively capturing a specific target molecule.

Abstract: Disclosed are cell membrane-derived nanovesicles, a method of preparing the nanovesicles, and a pharmaceutical composition and a diagnostic kit using the nanovesicles. The cell membrane-derived nanovesicles may prevent potential adverse effects because intracellular materials (e.g., genetic materials and cytosolic proteins) unnecessary for delivering therapeutic or diagnostic substances are removed from the nanovesicles. In addition, as the nanovesicles may be targeted to specific cells or tissues, therapeutic or diagnostic substances may be predominantly delivered to the targeted cells or tissues, while delivery of the substances may be inhibited. Therefore, the nanovesicles may alleviate suffering and inconvenience of patients by reducing adverse effects of therapeutic substances and by improving efficacy of the substances. In addition, the cell membrane-derived nanovesicles loaded with therapeutic or diagnostic substances 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: The present disclosure relates to a pre-5t-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for operating a transmitting stage in a wireless communication system includes generating a signal by encoding an input bit sequence according to polar code determined from a linear code, and transmitting the signal to a receiving stage. The input bit sequence includes a second frozen bit which is determined based on a first frozen bit and an information bit. The first frozen bit and the information bit precede the second frozen bit in the input bit sequence.

Abstract: Provided are: a light-emitting layer for a perovskite light-emitting device; a method for manufacturing the same; and a perovskite light-emitting device using the same. The method of the present invention for manufacturing a light-emitting layer for a halide perovskite light-emitting device comprises a step of forming a first nanoparticle thin film by coating, on a member for coating a light-emitting layer, a solution comprising halide perovskite nanoparticles including a perovskite nanocrystal structure. Thereby, a nanoparticle light emitter has therein a halide perovskite having a crystal structure in which FCC and BCC are combined; and can show high color purity. In addition, it is possible to improve the luminescence efficiency and luminance of a device by making perovskite as nanoparticles and then introducing the same into a light-emitting layer.

Abstract: A method for visualization of conjunctival cells using fluoroquinolone antibiotics and a method for diagnosis of ocular lesions using the same. The method for visualization of conjunctival cells using fluoroquinolone antibiotics includes staining goblet cells of ocular conjunctiva with moxifloxacin, which is a fluoroquinolone antibiotic, and exciting the stained goblet cells with single photons in the near-UV region or in the visible region, followed by fluorescence photographing of the goblet cells, thereby enabling acquisition of morphological information on living tissue without damage to or destruction of the ocular conjunctiva. Specifically, the method for visualization of conjunctival cells includes: a conjunctiva staining step in which ocular conjunctiva is stained with a fluoroquinolone antibiotic; a light irradiation step in which the ocular conjunctiva stained with the fluoroquinolone antibiotic is irradiated with light from a light source; and a conjunctiva photographing step in which the ocular conjunctiva is photographed using an image pickup unit through the fluoroquinolone antibiotic fluorescence-excited by light in the light irradiation step, wherein, in the conjunctiva staining step, goblet cells of the ocular conjunctiva are stained with the fluoroquinolone antibiotic; in the light irradiation step, the light source emits single photons; and, in the conjunctiva photographing step, the image pickup unit photographing the ocular conjunctiva is a high-magnification fluorescence microscope or a slit lamp microscope.
