Manipulation of the QD surface by changing morphology and surface capping ligands, as well as adjusting nanocrystal size, plays a crucial role on the selectivity and sensitivity exhibited by QDs towards a given target analyte. In this study, a novel aqueous synthesis of CdTe QDs capped with a thiol compound containing a sulfonate (SO3−) terminal group, viz., 2-mercaptoethanesulfonate (MES), was thoroughly investigated with the aim of obtaining a fluorescent probe for chemical analysis.
