Analysis of a single silver NP. Nine slices in the immediate vicinity of a single silver NP at a distance of 40 nm to each other are shown above the x-axis. The maximum intensity of each image is taken to calculate the escape depth of electrons. The escape depth for the particle shown is ~79 nm. The average escape depth for all 16 single silver NPs investigated in this fashion is 89 ± 17 nm. The escape depth is used to determine total normalized intensity of a segmented single SNP in our sample to be (89 ± 17)
