摘要：
A highly sensitive surface plasmon resonance (SPR) immunosensor combining antibody-functionalized Fe3O4magnetic nanoparticles (immunoMNPs) separation is reported for rapid detection of Salmonella enteritidis (S. enteritidis) based on the sandwich immunoassay. Here, immunoMNPs simultaneously served not only as "vehicles" for rapid delivery of analyte from a sample to the sensor surface, but also as labels increasing the measured refractive index changes associated with the binding of analyte. S. enteritidis can be detected at the concentration as low as 14 cfu/mL with a good linear signal range...
