Dynamic light scattering system
EF 2006-07
Résumé
We request a dynamic light scattering (DLS) system to pursue our research on polymer micelles. On one hand, we have established a general design principle for light-controllable polymer micelles, which opens the door to developing photoactive nanocarriers for controlled delivery applications. We need a DLS to quantitatively study the dissociation of our micelles upon light irradiation in order to understand the mechanism of their photodissociation and the relationship with other events such as the photoreaction and the release of encapsulated guests. On the other hand, we have demonstrated the use of the layer-by-layer (LBL) technique to assemble directly two polymer micelles with oppositely charged polyelectrolyte coronas, which offers a general strategy to organize hydrophobic polymers into layered and nanostructured thin films. We need a DLS to characterize our polymer micelles in order to understand the correlation between the micellar size and morphology in solution before and the properties and functions of the film after the LBL assembly.
