Although the spread DNA origami pieces initially remained in the monomer form, the repeated mechanical compression and expansion of the Langmuir monolayer induced the interconnection of the rectangle pieces into one-dimensional polymer motifs. The origami–origami connections were formed

By contrast, Cd–O bonds are much weaker than Pb–O bonds, so in the case of cadmium, the Langmuir (monolayer) adsorption model is

Known since about 80 years, LB films can be considered from many points of view as one of the prominent predecessors of what we call nanoscience today [1

• ). Using Equation 1 and the Young’s modulus of AAO of 340 GPa one can evaluate the quantity of water adsorbed onto the anodic alumina surface. The calculation gives a result of Δm = 20 pg at a sensitivity Δf/Δm of 56 Hz/pg. On the other hand, the amount of absorbed water can be estimated from the Langmuir

Taking into account the total area of the cantilever of 1.74·10−6 m2 (1.58·10−6 m2 interior and 1.63·10−7 m2 exterior area) and the density of the active sites of 4.8 nm−2 the maximal mass of a water monolayer adsorbed onto cantilever surface is 250 pg.
