|Abstract: ||Quantum dots (QDs) are semiconductor nanocrystals that exhibit distinctive photoluminescence properties due to the quantum confinement effect. We have developed a unique aqueous synthesis route to produce highly luminescent non-heavy metal ZnS QDs capped with carboxylated molecules in one single step. They differ from commercial quantum dots in that they do not contain toxic heavy metals and that they are very small, ideal for invivo biomarker applications. The carboxyl-capped QDs are 2-5 nm in size, biologically-benign, stable, and ready for conjugation with proteins or other biomolecules as fluorescence markers for molecular tracking and disease diagnoses.|
