Temporal change in the relative Ni content of the skin and the chemical states of Ni. Time-dependent change in Ni distribution in mouse skin (cross-section) following 30-min to 24-h application of Ni-nanoball packs (a); the time dependence of the total fluorescence X-ray intensity of Ni Kα (over the entire specimen area shown in Figure 4a) of the Ni-nanoball pack and a commercial patch (b); and Ni K-edge XANES spectra of Ni nanoballs (c) and permeated Ni in mouse skin (released from a Ni-nanoball pack) (d).
