Specific patterns of the cell jacket revealed by high resolution AFM imaging.

<p>A high density domain (patch) is encircled in white. Scan size 4.5×4.5 µm with vertical scale of 10 nm. The vertical profiles present the fibrils heights along indicated lines. The white coloured regions (up to 20 nm high) could represent inorganic or organic nanoparticles entrapped from the surrounding media.
