    • A tyrosinase enzyme electrode is provided to improve detection limit by introducing metal nanoparticles into the enzyme electrode, and induce activation of tyrosinase enzyme by introducing a substrate into the enzyme electrode, so that the enzyme electrode is useful for detecting remaining agricultural chemicals. A tyrosinase enzyme electrode comprises a substrate(100), a metal nanoparticle layer(120) formed on the substrate, a buffer layer(140) formed on the metal nanoparticle layer to form a self-assembled monolayer for fixing the tyrosinase, and a tyrosinase(160) formed on the buffer layer, wherein the metal nanoparticles are present in a separated particle type and include gold, silver, copper, palladium or platinum; the tyrosinase is immobilized on the self-assembled monolayer with a coupling agent with diimide group. A method for forming the tyrosinase enzyme electrode comprises the steps of: forming a metal nanoparticle layer on the substrate; forming a buffer layer on the metal nanoparticle layer; and fixing the tyrosinase on the buffer layer by introducing a coupling agent. Further, the substrate is made of glassy carbon.

    • A process of fabricating a metal nano-wire array using self-assembled super-molecular sieve with hexagonal cubic nano-structure is provided to produce the nano-wire individually serving as a memory medium unit and to possibly fabricate miniaturized optoelectronic devices by forming a complex of the super-molecular sieve and metal ions and forming a thin film of the complex on a substrate. The process includes the steps of: (a) preparing a complex of super-molecular sieve and metal ions by combining the molecular sieve with the metal ions; (b) forming a complex thin film by treating the prepared complex on a substrate; (c) forming a circular super-molecular sieve with alignment of metal ions by heat treating the complex thin film to induce a self-assembly of the molecular sieve; and (d) reduction reacting the metal ions aligned in the molecular sieve to form a metal nano-wire array with alignment of the metal ions. The super-molecular sieve has at least one functional group selected from a group consisting of carboxyl, amine, hydroxyl, aldehyde and thio groups.
