Dynamic light scattering schematic representation

Fig. 3.6 The relative intensity of dynamic light scattering vs. the diameter of scattering particles for a solution with 1 wt.% bovine serum albumin (1) and the same solution after addition of 3 wt.% of THEOS (2). Before the measurements, the solutions were left at ambient temperature for a week. The drawings are a schematic representation of a protein macromolecule before and after the treatment by silica precursor.

Schematic representations, like those shown in the Scheme 1, are very useful to indicate the chemical composition of the various species and to discuss the interaction between the various building blocks. Furthermore, as one can understand from the representations shown in Figures 9 and 10, the species with high nuclearity exhibit a ttu-ee-dimensional branching structure of the type of those shown by otherwise completely different dendrimers based on organic components. Therefore, endo- and exo-receptor properties can be expected, which are currently under investigation. Furthermore, aggregation of decanuclear complexes has also been demonstrated by dynamic light-scattering and conductivity experiments. Systematic studies on aggregation properties have, however, not been performed yet.
