METHOD OF DETECTING BIOPRODUCTS USING LOCALIZED SURFACE PLASMON RESONANCE SENSOR OF GOLD NANOPARTICLES

摘要

localized surface plasmon resonance of gold nanoparticles (Localized Surface Plasmon Resonance, LSPR) biomaterials with the phenomena relates to a detection method , the prepared gold nanoparticles immobilized on the glass plate after the antigen- a way to diagnose the biological material by using a maximum wavelength change via antibody reaction . High sensitivity sensor using this method , cheap , can be diagnosed in a short time 's disease diagnosis as well as environmental contaminants , and allows application to a variety of biological fields such as pathogens , cheaper than the method using the conventional SPR, fast , a technique for creating a sensor with higher sensitivity .
