Figure 1

This nanometer scale mapping is able to provide more accurate information of the elemental distributions in the tissue than that from micrometer scale mapping and, hence, reduce the uncertainty. The color bars show the concentration in the units of counts per second (cps). The dimension of the area is approximately 6 μm × 6 μm.
