Wet individual Single walled carbon nanotube was observed at an atomic level with high resolution. This observation
was achieved in a liquid cell containing water using a modified non-contact mode atomic force microscopy
(NC-AFM) which, we believed, becomes the powerful tool for imaging nano-material in atomic scale. Consequently, the
topography image showed many hexagons network of carbon atoms forming the outer surface of SWCNT. The analysis
of the scanned SWCNT, by NC-AFM probe, revealed the presence of two sites of an armchair and zigzag structures.
