area would result in a highly defined surface functionality of the probe down to single molecule level with high reproducibility.
Keywords: atomic force microscopy; click reaction; force spectroscopy; singlemoleculemodification; Introduction
Single-molecule force spectroscopy (SMFS) has become one
resulting larger contact area between probe and surface during force spectroscopy. The value of nav of the specific interaction was 1.1–1.5 for the Si probe, demonstrating a successful single-moleculemodification. Similar values of nav were obtained for the other three Si probes with a maximum value of 2.1
