Gold and Other Elements

Caption

This image shows maps of pure gold with other elements. By determining what elements there are, scientists can see where the gold is located in relation to the cells. These maps are quantitative X-ray fluorescence maps showing the distribution of gold, calcium, copper, iron, sulfur and zinc in an individual cell after a minute exposure to Au(III) at pH 7.0 (the quantified area is marked in the image, and concentrations are in the image).
