Acid-base interactions measurement monolayer

Atomic force microscopy makes it possible to calculate the adhesion forces between different interfaces. In this type of experiment, both the sample and the tip of a force microscope are coated with a functionahzed monolayer. The measurements of force v5 distance between the two surfaces allows one to estimate the strength of attractive interactions (if any) between them. Crooks and coworkers obtained the following energy values for H-bond interactions NH2 vi NH2 1.3, COOH vs COOH 5 and COOH vs NH2 16 kcalmoP. Although adsorbed water molecules may have affected these data, they scale well with those expected for H-bond and acid-base interactions. ... [Pg.609]
