A Review of the Application of Quantum Dots as Probes in Fluorescent Immunoassays of Low Molecular Weight Food Contaminants

doi:10.7506/spkx1002-6630-201619049

Abstract

Abstract:

Quantum dots (QDs) are semiconductor nanoparticles with very interesting optical properties like high quantum
yield, and narrow and size-tunable fluorescence spectra. QDs are applied widely, especially as fluorescence labels in food
safety detection that has received increased attention recently. In this review, three methods for coupling antibody/antigen
to QDs are discussed. The development of QD-based fluorescent immunoassays for the detection of low molecular weight
hazardous compounds in the food safety area is also demonstrated.

Key words: quantum dots, conjugation, food safety, low molecular weight compounds, fluorescent immunoassays
