Tip to substrate distances in STM imaging of biomolecules.

Ultramicroscopy - 1 Nov 2004

Alliata Dario, Andolfi Laura, Cannistraro Salvatore

Abstract excerpt

STM images of single biomolecules adsorbed on conductive substrates do not reproduce the expected physical height, which generally appears underestimated. This may cause the tip to interfere with the soft biological sample during the imaging scans. Therefore, a key requirement to avoid invasive STM imaging is the knowledge, and the control, of the initial tip to substrate distance. This is connected to the...
