Abstract: PURPOSE: A method for manufacturing an optofluidic element in which a metallic sphere gap nano structures are accumulated is provided to reduce costs and time for a process and simplify a process condition by using a self-assembly phenomenon of colloid. CONSTITUTION: A method for manufacturing an optofluidic element in which a metallic sphere gap nano structures are accumulated comprises next steps. Colloid particle layer of a single story, in which colloid particles are regularly arranged, is formed on the top of a polymer thin film, thereby being dipped into the polymer thin film. The colloid particles dipped into the polymer thin film are eliminated so that a spherical pore structure of a nano meter scale is formed on the polymer thin film. A metallic thin film is deposited so that a metallic thin film in the inside of a gap and the metallic thin film on the top of the polymer thin film are discontinuously formed. A patterned metallic structure is manufactured by using an UV-crosslinkable polymer. Minute flexible fluidic elements are integrated in the patterned metallic structure.
