Inorganic nanoparticles in functional matrices
We are interested in embedding metal and metal oxide nanoparticles into (coordination) polymer matrices to prepare functional materials for biomedicinal and environmental applications.
For instance, we synthetize Fe3O4-MOF core-shell nanoparticles which can be used in medicine as agents combining drug delivery with magnetic resonance imaging (MRI), magnetic targeting, or magnetic hyperthermia.
To study such complex materials, we use advance electron microscopy techniques (SEM and TEM) including elemental mapping (EDS and EELS) and tomography.
