In this section, interactions between single cells and metal elements are investigated via the measurement of the density ﬂuctuation and also of the localization of those elements, in single cells that have been cultured in a metallic solution environment. 1 Macrophages Macrophages are widely distributed throughout the body, displaying great structural and functional heterogeneity. 2 Elemental Images of Single Macrophage Cells 49 organs, the liver, lungs, gastrointestinal tract, central nervous system, serous cavities, bone, synovium, and skin.
The black solid and dotted lines show the untreated spectrum and the estimated background respectively, and blue dotted line shows the peak obtained by the ﬁtting. It can be seen the ﬁtted Gaussian corresponds well to the measured spectrum. 24) where a, b, c and d are the variables determined by the properties and conﬁguration of the multi-channel analyzer and the detector . 5 Quantitative XRF Analysis 29 These expressions are utilized in the multiple peak ﬁtting. , P, S, Cl, Ar, K, Ca, Sc, V and Zn).
5 Quantitative XRF Analysis 25 is applied to each single peak in which the width, position and height of the peak are adjusted. In the last process, the concentrations of the elements in the biomedical specimens are quantiﬁed by comparing the peak areas obtained in the second process to those of reference samples obtained in the ﬁrst process. The algorithm and the basic equation utilized in the program are described detailed in the following section. Estimation of the Background Quantitative analysis using XRF spectra requires the removal of the background prior to the estimation of the net area of the peaks.
