19. Triangular shaped silicon nitride cantilevers with silicon nitride tips (Digital Instruments (DI), Santa Barbara, CA, USA), which were coated with 2 nm Ti and 75 nm Au in high vacuum (Balzers), were functionalised with 11-hydroxyundecanol following the procedures described in refs. 8 and 9. The SFM measurements were carried out with a NanoScope III multimode SFM (DI) with modified tips in buffered aqueous solutions of constant ionic strength utilising a liquid cell (DI). The force distance curves used for construction of force titration curves were obtained with at least 10 different positions for each sample. For laterally resolved pull-off force measurements the AFM was operated in the force volume (FV, DI) mode. Only subsequent up and down scans which showed the same force characteristics were considered.
20. A strict quantitative evaluation, such as described by Hu and Bard (K. Hu and A. J. Bard, Langmuir, 1997, 13, 5114), is at this point not possible due to uncertainties of the tip shape (granular gold coating) and the unknown effect of the morphology of the polymer films.
