Quantum dots (QDs) technology is commonly used in medical application as a probe for
diagnostic procedures via imaging macroscopic and microscopic structures in life sciences.
Also they can be used for designing of biosensors. However, the application of this
technology is very new in food science. In this study, a novel application of QDs in food
science was investigated. QDs were conjugated to gliadin antibody and used as a
fluorescent probe to track gliadin protein in dough and baked bread samples. The type and …

In this study, Quantum dots (QDs) were conjugated to gliadin antibodies and used as
fluorescent probes to track gliadin proteins in dough and baked bread samples. QDs
conjugated to gliadin antibody were specifically bound to gliadin to determine its molecular
distribution in two different unleavened flat bread samples prepared at various baking times
and compared with the uncooked dough. The specificity of gliadin antibody to gliadin was
shown successfully with a Western Blot experiment excluding binding to all other hard wheat …
