Abstract: The present invention relates to an electrolyte containing a polydopamine and a lithium-sulfur battery including the same and, more particularly, to a technique in which polydopamine contained in an electrolyte adsorbs a lithium polysulfide eluted from a positive electrode of a lithium-sulfur battery. When using an electrolyte, according to the present invention, to which polydopamine particles are added, the polydopamine particles dispersed in the electrolyte act to adsorb lithium polysulfide eluted from a positive electrode during the charging and discharging, and thus can suppress the diffusion thereof, i.e., suppress a shuttle reaction, thereby improving the capacity and lifetime characteristics of the lithium-sulfur battery.

Abstract: The present invention provides facile and accurate molecular diagnosis of disease-specific genes capable of the naked eye detection through amplifying the target genes to selectively block the fluid path in a microfluidic device. Specifically, the present invention includes an isothermal amplification of target genes through a rolling circle amplification, a microfluidic device for detecting pathogen genes, and a detection method using the same. Therefore, the present invention can conveniently detect a single target gene, such as a single pathogen, or at the same time, several target genes, such as several pathogens, without complicated mechanical equipment.
