Differences in Cytotoxic, Genotoxic, and Inflammatory Response of Bronchial and Alveolar Human Lung Epithelial Cells to Pristine and COOH-Functionalized Multiwalled Carbon Nanotubes

<table>Representative optical microscopy images of BEAS-2B cells exposed for 24 h to CNTs before washing them to remove CNTs dissolved in the medium. (a) Cells exposed to 40 <i>μ</i>g/mL of pristine MWCNTs; (b) cells exposed to 40 <i>μ</i>g/mL of MWCNT-COOH; (c) control cells. Magnification: 20x. TEM micrographs of pristine MWCNTs (d) and MWCNT-COOH (e) agglomerates/aggregates in BEGM culture medium (bar: 2 <i>μ</i>m).</table>
