Chemical force microscopy (CFM) was used to measure the adhesion force between an Au-coated Si3N4 tip functionalized with OH groups and a silicon substrate functionalized with NH2 groups. The curve of the adhesion force as a function of the solution pH value (force titration curve) was obtained. The...
