Abstract: The present invention relates to a kit for construction of drug-containing nanoparticles and a nanoparticle composition for drug delivery. More specifically, the present invention concerns a kit for construction of drug-containing nanoparticles and a nanoparticle composition for drug delivery, each designed to increase the efficiency of cellular drug delivery by utilizing nanoparticles that include a cationic compound and an anionic polymer compound with at least one acidic functional group.

Abstract: The present invention relates to a composition forming nanoparticles for delivering a drug, and more specifically, to a composition for drug delivery comprising nanoparticles containing cationic compounds and a polylactic acid salt but not containing an amphiphilic polymer, wherein a drug can easily be incorporated into the nanoparticles by simply mixing the drug therewith, and furthermore, cell delivery efficiency of the drug can be further increased compared to nanoparticles containing an amphiphilic polymer.

Abstract: The present invention relates to a kit for preparing nanoparticles containing a drug and, more specifically, to a kit for preparing drug-containing nanoparticles, the kit enabling a drug to be easily contained in nanoparticles by simple mixing only, preferably, in a specific weight ratio, the drug and nanoparticles containing a cationic compound and a polylactate, as kit constituent components comprising no amphiphilic polymers, and being designed to enable the efficiency of drug delivery into cells to be greater than that of a kit comprising an amphiphilic polymer.

Abstract: A chip electronic component may include an internal coil structure for preventing the occurrence of short-circuits between coil patterns and may have a high aspect ratio (AR) by increasing a thickness of the coil with respect to a width of the coil. The chip electronic component may include a magnetic body including an insulating substrate; an internal coil part formed on at least one surface of the insulating substrate; external electrodes formed on at least one end surface of the magnetic body and connected to the internal coil part. Insoluble films may be formed on side portions of coil patterns forming the internal coil part, and the internal coil part may have an aspect ratio of 1.5 or greater.

Abstract: There are provided a multilayer ceramic capacitor, a printed circuit board including the same, a method of manufacturing the multilayer ceramic capacitor, and a method of manufacturing the printed circuit board. The method of manufacturing a multilayer ceramic capacitor includes: preparing a capacitor body on which external electrode material layers are formed, dry polishing the capacitor body such that surfaces of the external electrode material layers are smooth and compact, and forming plating layers on the surfaces of the external electrode material layers in order to form external electrodes. Therefore, the surface smoothness, compactness, and uniformity of an external electrode plating layer can be improved.
