AB  - Some studies on quantum dots (QD) as donors that enhance the fluorescence of a 
      dye as an acceptor through fluorescence resonance energy transfer (FRET) have 
      been reported. However, in the present work we discovered that CdS quantum dots 
      sharply quenched the fluorescence of acridine orange (AO). Also, DNA enhanced the 
      fluorescent signals of AO quenched by CdS. The extents of enhancement were in 
      good proportion to the DNA concentrations. Based on this, a sensitive method was 
      employed to determine DNA with both good selectivity and sensitivity. The 
      calibration curve was linear over 60-4,000 ng mL(-1) and the determination limit 
      (3sigma) was 4.39 ng mL(-1).
