A simple quantum dot-based fl uoroimmunoassay method for selective capturing and rapid detection of Salmonella Enteritidis on eggs

Abstract

The aim of this paper was to demonstrate a rapid and selective fluorescence-linked immunoassay method based on quantum dots as the fluorescent marker for the detection of Salmonella Enteritidis on eggshell. Highly-fluorescent and water-soluble CdTe quantum dots were prepared by using thioglycolic acid and 1-thioglycerol as ligands and were then conjugated… (More)
