ABSTRACT:
Apparatus for the high resolution imaging of macromolecules and interactions involving macromolecules. The apparatus comprises a surface (10) on which the macromolecule under test is placed and a plurality of fine probes (13). Means (not shown) are provided for scanning each of the probes (13) across a small area of the surface 10 in such a way that the total output from the probes covers the whole surface. Means (not shown) such as a scanning tunnelling and/or atomic force detector are used to monitor the movement of the individual probes in a direction transverse to the surface (10) and display means (not shown) are used to display the transverse movement of the probes, being illustrative of the topography of the surface.
