ABSTRACT
Investigates the lubrication properties of a simple surfactant on mica using atomic force microscope. Lubrication properties of the adsorbed molecules; Observation of friction signal when layer of molecules are removed; Domination of adhesive forces over tip-mica interaction; Influence of the effective area of the tip on the measured friction and normal forces.

    An atomic force microscope using optical lever detection has been used to study the friction between muscovite mica and a tungsten tip. The frictional force is shown to vary laterally with the periodicity of the hexagonal layer of SiO4 units that forms the cleavage plane of mica. The frictional...

    The volume of a single surfactant molecule is measured by atomic force microscopy. Experimental data demonstrate good agreement with the calculated data. This approach can be applied to a large variety of surfactant molecules that form flat bilayer structures visualized by a microscopic technique.

    Using fluorescence microscopy (FM), which permits the observation of single molecules, we found that a pearling structure is generated on a single long DNA molecule upon the addition of a gemini (dimeric) surfactant. This pearling structure was further investigated by performing atomic force...

    We demonstrate that the absolute separation between an atomic force microscope (AFM) tip and a solid substrate can be measured in the presence of an irreversibly adsorbed polymer film. The separation is obtained from the analysis of a scattered evanescent wave that is generated at the surface of...
