Life-cycle of nanomaterials in biological media

publié le , mis à jour le

In spite of the exponential boom of the industrial and biomedical applications of inorganic nanomaterials, their impact on health is still poorly known, on account of the lack of methods for assessing at relevant scales the interactions between synthetic and living species in complex biological environments. Through close collaboration with the group of Florence Gazeau from the Laboratory Matière et systems complexes (Paris-Diderot University), we have developed original nanometrological methods to study the relation between the structure and the life-cycle of nanomaterials in the organism. Based upon our know-how in materials science, our multi-scale approach combines global magnetic and elementary analyses to quantify the biodistribution and transformation of nanomaterials at the tissue level (macro-scale) and the multi-functionalities of electron microscopy to reveal the biodegradation and recycling processes at atomic level. To provide a deeper understanding of the biotransformation processes, these multi-scales analyses are performed in biological media of different complexity, including : (i) model solution mimicking cellular environment, (ii) cell cultures (in vitro) and (iii) directly into mice (ex vivo analyses on extracted tissues). Beside conventional TEM analyses, the MeANS group has also developed in situ TEM methods to follow the behavior of nanomaterials directly in model solutions and in cell cultures. This methodology has been applied to promising nanomaterials for biomedical applications, including magnetic (Fe and Co nano-oxides), plasmonic (gold) and graphitic (nanotubes) nanostructures. This interdisciplinary researches are of primary importance for both material scientists interested in the modifications of nanostructures that affect, more or less quickly, their properties in vivo and biologists anxious to evaluate the effects and potential risk of nanomaterials for human health.
