As the lateral position is measured from the apex of the probe, analysis of the data will indicate the width of the feature to be greater than it actually is. The recorded width of the dsDNA helix, for example, when analysed using AFM is typically 12–15 nm, whereas a width of 2 nm is predicted from the crystal structure. 6 A schematic explaining the origin of probe–sample convolution. As the probe approaches the object to be imaged, (a) and (b), the side of the probe makes contact first, causing a premature rising of the cantilever.

This method of imaging is known as contact mode. Alternatively it is also possible to image with the probe located further from the surface where attractive probe–sample forces dominate. In this region the specimen can be imaged without the probe ever coming into contact with the surface, and hence this imaging method is known as noncontact mode. 1 Contact mode In contact mode, the AFM probe is brought into direct physical contact with the sample surface. The probe is traced along the surface, and the cantilever deflects in response to changes in the repulsive probe-sample forces which occur due the sample’s topology.
