Diluted solution (10µg/ml) of multi-wall carbon nanotubes (lenght = 400nm) is deposited on a T-Surf (specific contrast-enhanced microscope slide provided by Nanolane company). The brownian motion is observed in real-time with a standard optical microscope (Sarfus technique). No labelling, nor pre-treatment is needed.
