Chemical force microscopy (CFM) was used to follow the dissociation process of 4-mercapt-opyridine (4-MP) self-assembled monolayers (SAMs) on gold. The force probe was an Au-coated Si3N4 tip modified with 4-MP SAM. The adhesion force between tip and substrate was found to be a function of solution p...
