Polymer shell structure of irreversibly stabilized superparamagnetic nanoparticles and their assembly into membranes
Superparamagnetic iron oxide nanoparticles (SPIONs) are intensively researched for biomedical imaging and drug delivery applications. Their functionality in such applications strongly depends on the density profile of the polymer shell grafted to the magnetic inorganic core. SPIONSs can also be used as building blocks for self-assembled superstructures, e.g. at liquid interfaces; likewise the shell distribution at the interface determines the structure and functionality of the assembly. We will use SANS to complement our current thorough characterization by determining the shell structure of individual state-of-the-art SPIONs as well as assembled in emulsome membranes.
