Dendrimer-dye electrostatic self-assembly: a time-resolved SANS study.
Self-assembly is an effective method to produce complex macromolecular structures of interest for example in nanotechnology or as carrier systems. Recently we have introduced a new concept of electrostatic self-assembly for the formation of well-defined supramolecular nanoscale assemblies of various shapes in solution. As part of the ILL PhD project, the goal of this experiment is to provide insight into the structure formation mechanisms. The model system under investigation will consist of a cationic poly(amidoamine) generation four dendrimer and a divalent anionic sulfonate dye (Ar26) and a trivalent one (SuAVAc). The system will be studied by SANS using a new, improved, mixing cell. This will be crucial for studying the process time resolved and in detail. These experiments will be part of the project of the ILL-PhD student Giacomo Mariani, the long-term objective of which is to gain fundamental insight into dynamic structure directing effects in the self-assembly.
