29. AFM images of mica surfaces that had been incubated in a 0.05 mg/mL dendrimer/toluene solution and then removed and dried suggest the surfaces are coated with dendrimer films of similar thickness. The extent of coverage varied from a fully covered surface (continuous unbroken dendrimer layer) to one where irregular holes formed in an otherwise fully coated surface. These holes may have formed as a result of solvent evaporation.

31. The refractive indices of the dendrimer and of toluene - and thus their Hamaker constants - are similar, so that the dendrimer layer, to a first approximation, does not significantly change the van der Waals forces between the mica sheets across the dendrimer/toluene sandwich in the gap relative to pure toluene.

38. The Derjaguin approximation enables the conversion of the force data F(D) between the curved mica surfaces (mean radius R) a closest distance D apart to the interaction energy per unit area E(D) = F(D)/2πR between parallel plates a distance D apart.
