PREPARATION METHOD OF GOLD NANO ELECTRODE USING ELECTROCHEMICAL CO-DEPOSITION OF GOLD AND VIRUS FOR DETECTING NITRITE ION

摘要

The present invention relates a preparation method of a gold nano electrode using electrochemical co-deposition of gold and virus for detecting a nitride ion and, more specifically, relates to a preparation method of a gold nano electrode for detecting a nitride ion, wherein through M13 virus (wild type and designed in the form of M13-Y3E or M13-4E) and gold (Au) deposition for co-deposition in an electrode (ITO), a gold nano structure with excellent electrochemical reaction with respect to nitride ion detection and measurement can be manufactured with a simple method. According to the present invention, a manufactured nano electrode can selectively react to only a nitride ion under existence of a lot of interfering substances, and a nitride ion of which an electrode has low concentration of 100 μM is selectively detected.
