| Abstract: |
Shear force mapping on thiolipid Langmuir-Blodgett monolayers probed with Al-coated tips leads to a contrast highly dependent on the monolayer molecular organization, which does not correspond to the topographical relief of the sample. The use of functionalized surface probes offers the possibility to better control the probe-to-sample interaction. In addition, hydrophilic surface probes are totally insensitive to alkyl chain arrangements in the monolayer. Hydrophobic probes, instead, can be chosen to map shear force on soft samples in liquid environment, since their mechanical properties are not influenced by the surrounding liquid.
