Fig. 1

SEM images of particles on the substrate surface and cross-section images of a coarse-pored (a and c) and a fine-pored nanosponge (b and d). e Cross-section image of the the fine-pored sponge taken with the Inlens secondary electron (SE) detector. f Segmentation of the image e performed with a grayscale threshold of 60 in the 8-bit range.
