Abstract

Iron oxide nanoparticles are promising candidates for applications in nanomedecine (contrast agents, vectors). They were also recently considered as a powerful tool for tissue engineering. Cells, magnetized through nanoparticules internalization, can be organized in space and time thanks to remote magnetic forces. For all those applications the nanoparticles fate inside the cells remains a key issue concerning the final clinical use. The first part of this work focuses on the study of the mechanical and rheological properties of biological tissue models, the multicellular aggregates. An original magnetic molding method and two different experimental setups were developed to produce aggregates with controlled shapes and sizes, to measure th...
