AFM - is the van der Waals force between the tip and the surface; this may be either the short range repulsive force (in contact-mode) or the longer range attractive force (in non-contact mode).

Scanning Probe Microscopy (SPM) is a group of methods, like Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM), that uses a probe to sense a probe-to-surface atom interaction. By two-dimensional scanning of the probe on the surface, a high resolution microscopic image is produced.

the tales of the smp
AFM's have poor depth of field, but provide amazing contrast on flat samples. The unique capabilities of the SEM and AFM are demonstrated in such extreme examples as the SEM's ability to image a fly's head, and the AFM's ability to image structures on polished silicon.
The CNTs were originally suspended in n-dimethylformamide (n-DMF). After being sonicated for approximately 10 minutes, the solution was dropped onto a piece of highly oriented pyrolitic graphite (HOPG). The AFM was developed to overcome a basic drawback with STM - that it can only image conducting or semiconducting surfaces.
