| pubmed-article:21611650 | pubmed:abstractText | A new approach for the detection of Hg(2+) is reported based on color changes from which gold nanoparticles (Au NPs) are surrounded by a layer of HgS quantum dots to form in situ Au@HgS core-shell nanostructures. The surface plasmon resonance (SPR) absorption of the gold core was changed due to a shell layer of HgS formed on the surface of the Au NPs, which brings the colour change of the aqueous solution. Therefore, Hg(2+) can be recognized by visualizing the colour change of the Au@HgS core-shell nanostructures, and can be detected quantitatively by measurement of the UV-vis spectra. Some effects on the detection of Hg(2+) were investigated in detail. This method was used to detect Hg(2+) with excellent selectivity and high sensitivity. In our method, the lowest detected concentrations for mercury ions were 5.0 × 10(-6) M observed by the naked eye and 0.486 nM as measured by UV-vis spectra. At the range from 8.0 × 10(-5) to 1.0 × 10(-8) M of Hg(2+), this method was shown to have a good linear relationship. | lld:pubmed |
