The hemolysis assay remarkably predicts the inflammatory potential of inhaled particles. The capacity of particles to damage cellular membranes is a key property to predict their inflammatory potential upon inhalation. In macrophages and epithelial cells exposed to particles, alteration of the

HR MAS analysis of intact tissues consists in the metabolic profiling of entire tumor biopsies using high resolution NMR (nuclear magnetic resonance) using 1H and/or 13C MRS (magnetic resonance spectroscopy). The technique allows combination of metabolomic data with genomic or proteomic data, and
