Abstract

(EN)Disclosed is a method of detecting bioproducts using Localized Surface Plasmon Resonance (LSPR) of gold nanoparticles, which can diagnose bioproducts based on changes in the maximum wavelength occurred by an antigen-antibody reaction after immobilization of the gold nanoparticles onto a glass panel. A sensor using such method exhibits high sensitivity, is low in price, and makes quick diagnosis possible, thereby being applicable to various biological fields associated with environmental contaminants, pathogens and the like, as well as diagnosis of diseases. Further, it provides a technology for manufacturing a sensor having higher sensitivity, low price and quick performance, as compared to conventional methods using SPR.
