摘要： The prepared CdSe quantum dots (QDs) were applied to selectively and sensitively assay ciprofloxacin as a fluorescence sensor based on fluorescence resonance energy transfer (FRET) mechanism. The efficiency of FRET between CdSe QDs and ciprofloxacin can be modulated by the degree of spectral overlap between the excitation peak of CdSe QDs and the emission peak of ciprofloxacin. Within the range of 0 to 120 mu mol.L-1, the good linearity was obtained (R = 0.99561) and the detection limit reached to 0.6 mu mol.L-1. This method is simple and rapid and can be used in environmental water and milk samples.
