Figure 2From: Free radical scavenging and formation by multi-walled carbon nanotubes in cell free conditions and in human bronchial epithelial cellsTransmission electron microscopy (TEM) analysis on nanomaterials (1330 μg/ml, corresponding to 350 μg/cm2) in exposure medium (BEGM + 0.6 mg/ml BSA). Dispersions are shown in two magnifications (the measure bar is 2 μm in the upper images and 0.2 μm in the lower images).Back to article page
