ELECTROCHEMICAL IMMUNOASSAY SYSTEM UTILIZING GOLD PARTICLE-BONDING SILICA NANOPARTICLES, AND ELECTROCHEMICAL IMMUNOASSAY METHOD AND ELECTROCHEMICAL IMMUNOASSAY DEVICE USING SAME

摘要

The present invention provides an electrochemical immunoassay system and an immune sensor having high sensitivity through amplification of electrical signals. To this end, the electrochemical immunoassay system using gold (Au) particle-bonding silica nanoparticles comprises: a gold (Au) electrode layer; a first antibody fixed on the gold (Au) electrode layer; an antigen to be detected by reacting to the first antibody; a second antibody combined on the antigen to be detected; and gold (Au) particle-bonding silica nanoparticles combined on the second antibody.;COPYRIGHT KIPO 2015
