Abstract:
The present invention relates to a method for reforming hydrophilicity on the surface of a channel inside a micro-fluidic device and a micro-fluidic device. Specifically, the present invention relates to a method for rapidly conducting reaction and inspection experiments by reforming a channel of a micro-fluidic device into hydrophilicity in order to make a rapid fluid flow inside the channel. In addition, the method prepared by the present invention is a clean process which does not generate toxic substances using a vacuum evaporation method for coating with a hydrophilic material. Therefore, the method can perform hydrophilic coating in quantity at a time, can form stable hydrophilic coating at room temperature without any influence of changes in the environment, and can be applied to a micro-fluidic element which requires optical reading by providing high transparency when formed at an appropriate thickness.

PURPOSE: Fluorescence nano particles and a method for manufacturing the same are provided to prevent the leakage of fluorescence dye in the core of the nano particles by locating the fluorescence dye in the core. CONSTITUTION: Fluorescence nano particles include a core and silica coated on the core. The core is obtained by the combination of fluorescence dye and polysilane. The fluorescence dye is one or more selected from a group including fluoresceinisothiocyanate, 4'-6-dianmidino-2-phenylindole, rhodamine 6G, and Tri(2,2 -bioyridyl)ruthenium(II)chloride. The fluorescence dye and the polysilane are mixed with the mixed solution of water and surfactant. Silica is added to the mixed solution. A basic material is added to the mixed solution in order to obtain the fluorescence nano particles.
