| 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. |
