Abstract:
PURPOSE: A manufacturing method of gold nano-particle pattern having a localized surface plasmon resonance combination phenomenon and a gold nano-particle pattern by the same are provided to control form and arrangement of gold nano-particles by controlling evaporation degree of the gold nano-particles. CONSTITUTION: A manufacturing method of gold nano-particle pattern comprises the following steps: manufacturing a reverse micelle solution by dissolving a self-assembly double block copolymers in a solvent; manufacturing the self-assembly double block copolymers reversed micelle thin film by coating the reversed micelle solution; inducing reconstruction of the reversed micelle thin film; and adsorping the gold nano-particles on the reversed micelle thin film by using a citrate ligand. The self-assembly double block copolymers comprise an amphiphilic diblock copolymer. The solvent selectively dissolves only one side block of the self-assembly double block copolymers. The reversed micelle solution contains 0.1-1 weight% of the self-assembly double block copolymers.

CONSTITUTION: A hybrid nanostructure thin film type photocatalyst includes a hybrid carbon-titanium dioxide nanostructure thin film or a silver-titanium dioxide nanostructure thin film. A method for manufacturing the hybrid carbon-titanium dioxide nanostructure thin film includes the following: A reverse micelle solution is prepared b dissolving an amphiphilic diblock copolymer in a solvent. A titanium precursor is dissolved in a solvent to obtain a titanium dioxide sol-gel precursor solution. The reverse micelle solution and the sol-gel precursor solution are mixed and are spin-coated to obtain a titanium dioxide-diblock copolymer thin film. Ultraviolet ray is irradiated to the thin film and is thermally treated to carbonize or eliminate the diblock copolymer.

PURPOSE: A method for preparing a protein nano array having pattern using self-assembled block copolymer thin film is provided to selectively adsorb a protein on self-assembled block copolymer thin film. CONSTITUTION: A method for preparing a protein nano array having pattern comprises: a step(step 1) of spin-coating a random copolymer which is dissolved in solvent to form neutral surface layer; a step(step 2) of spin-coating a block copolymer on the neutral surface layer to apply; a step of performing thermal treatment of the block copolymer to induce self-assembly and prepare template having regular structure; a step(step 4) of immersing the template in a protein solution to prepare protein nano array on which protein is adsorbed; and a step(step 5) of washing the protein nano array to form nano pattern. The random copolymer is polystyrene-polybenzocyclobutene-polymethylmethacrylate(P(S-r-BCB-r-MMA)). The protein of step 4 is a functionalized protein which is able to perform target specific bond.
