Water-soluble CdSe/ZnS quantum dots (QDs) were prepared via a simple sonochemical procedure using b-cyclodextrin (CD) as surface coating agent. The QDs displayed a sensitive emission enhancement for anthracene over other related polycyclic aromatic hydrocarbons, and the detection limit was around 1.6 10 8 mol/L.
