    • In the experiment performed by Oesterhelt et al. thiol and butoxy terminated PEG molecules were placed in hexadecane. The molecules were allowed to adsorb on a gold surface, after which an AFM tip was employed for stretching. Once adsorption of a PEG molecule on the tip occurred, the latter was moved away from the grafting surface in a direction perpendicular to it. The resistive force as a function of chain extension was recorded for several chain lengths. It was verified that the obtained curves are fully reversible by recording the trace backwards (tip moving toward the grafting surface) and retrieving identical results. When normalized by their contour length, all curves were found to superimpose. This is in agreement with our findings on the chain limit behavior. A rigorous statistical mechanical analysis of the polymer-cantilever system is made by Kreuzer et al. (Ref 28).
