Paper Abstract

The application of the STM and AFM techniques to imaging of biomolecules is reviewed. It is shown that in order to image poorly conductive molecules of nanometer dimensions, the STM has to be operated at high gap resistances in the 1012 ohm range. The correlation between forces and currents between tip and surface is investigated in model organic films of alkylsiloxanes on SiO2/Si(100) surfaces. The application of the AFM in the attractive and repulsive modes is also reviewed.
