- 中文摘要: CdS Quantum dots (QDs) are synthesized in aqueous solution with bovine serum albumin (BSA) as the stabilizing agents using a stepwise procedure at room temperature. They can be used as a new fluorescence probe in the determination of Cu2+, which is proved to be a simple, rapid and specific method. Approximate concentrations of other physiologically important cations, such as Zn2+, K+ etc, have no effect on the fluorescence. Under the optimum condition, the response is linear to the concentration of Cu2+ in the range of 0-80.0μmol/L, and the detection limit is 50.0 nmol/L. This method is used to the determination of Cu2+ in human hair, the recovery is 98-104%. And the possible detection mechanism is also discussed.
