Functionalised Thin Multi-Walled Carbon Nanotubes Are Less Toxic to Lung Cells In Vitro Than Their Native Counterparts

Scientists investigated the induction of the epithelial-mesenchymal transition of human bronchial epithelial cells BEAS-2B following six weeks of treatment with multi-walled carbon nanotubes ranging from 0.125 to 1 µg/cm².
