Water-soluble CdSe/ZnS quantum dots (QDs) were prepared via a simple sonochemical procedure using β-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.
