METHOD FOR MANUFACTURING A BIOSENSOR AND THE BIOSENSOR MANUFACTURED BY THE SAME, CAPABLE FOR APPLYING TO THE EXISTING SENSOR EQUIPMENT WITHOUT THE OVERALL REPLACEMENT OF THE SENSOR EQUIPMENT

摘要

PURPOSE: A method for manufacturing a biosensor and the biosensor manufactured by the same are provided to control the roughness of a metallic thin film surface, thereby enabling to regulate the detection sensitivity of the biosensor.;CONSTITUTION: A method for manufacturing a biosensor is as follows. A metallic thin film layer is formed on a base substrate(S110). Solution containing metal salt and a reducing agent which concentration are regulated is manufactured for controlling the roughness of a metallic thin film surface(S130). The base substrate where the metallic thin film layer is formed is dipped into the solution containing the metal salt and a reducing agent(S150). Metallic nano-protrusions are formed by a reduction reaction of a metallic ion on the metallic thin film layer surface(S170). The surface roughness of the metallic thin film layer is increased(S190).;COPYRIGHT KIPO 2013;[Reference numerals] (S110) Forming a metallic thin film on the top of a base substrate; (S130) Preparing a solution containing metal salt and a reducing agent; (S150) Dipping the base substrate in the solution containing the metal salt and the reducing agent; (S170) Forming nano-protrusions on the metallic thin film; (S190) Forming a metallic thin film with an increased surface roughness;
