摘要

The effect of heavy metal ions on the fluorescence of semiconductor ZnCdS nanoparticles in albumin solution has been studied. It is found that the fluorescence intensity of ZnCdS nanoparticles depends on the albumin concentration in the solution. Interacting with ZnCdS nanoparticles, heavy metals differently affect the fluorescence intensity of the nanoparticles. Copper ions induce fluorescence quenching, cadmium ions increase the fluorescence intensity, and zinc ions do not affect the fluorescence intensity. ZnCdS nanoparticles are the most sensitive to copper ions. Albumin enhances the effect of copper ions. The results on the influence of heavy metals on the fluorescence intensity of ZnCdS nanoparticles can be used to create a selective sensor for determination of copper ions in proteins using fluorescence quenching.
