Effects of the ionic strength on the supramolecular electrostatic self-assembly of dendrimers-dyes
Complex macromolecular structures that can respond to external triggers can be obtained by self-assembly through non-covalent interactions. Recently we have introduced electrostatic self-assembly as a new concept for the formation of well-defined pH-triggerable supramolecular nano-objects in aqueous solutions. So far, the structure of the nanoparticles has been characterized in detail, finding that it is strongly related to the thermodynamical parameters of the interaction between polyelectrolytes and counterions. Goal of this experiment is to fundamentally understand the electrostatic interaction between the polyelectrolyte and the counterions and the electrostatic stabilization of the nanoparticles. To achieve this the structure of the particles will be investigated as a function of the ionic strength of the solution and of the electrostatic screening.
