3-Mercaptopropyl acid-capped quantum dots (QDs) synthesized in aqueous solution were coupled to avidin-sulforhodamine, also named avidin-Texas red (ATR), via electrostatic attraction. An intensity reduction in the fluorescence emission spectrum of QDs and an enhanced fluorescence intensity of the dye were observed on account of fluorescence resonance energy transfer from the QD donors to the dye acceptors. In addition, the fluorescence characteristics of the QD-ATR conjugates were strongly-related to the quantity of ATR, pH value and ionic strength.
