Fig. 5From: Quantification of silver nanoparticle uptake and distribution within individual human macrophages by FIB/SEM slice and viewCluster size distribution of uptaken silver NPs. Histogram and cumulative distribution function of all silver NPs within the cell. The absolute dose of silver NPs within the cell was 3138 ± 722. Although only a few clusters with a size larger than 20 NPs were present in the cell, most NPs were located in these larger clusters (~53%). Only 9% of all silver NPs were found in very small clusters (cluster size 1–5, corresponding histogram not shown). The binning width for the histogram is 10 silver NPs. The left y-axis corresponds to the histogram and the right y-axis to the cumulative distribution functionBack to article page
