Dispersion, Characterization and Uptake of Multi-Walled Carbon Nanotubes by Epithelial Cells

Abstract:

Multi-walled Carbon Nanotubes (MWCNTs) have a great potential for microelectronics, optics and in biomedical applications (e.g. as nanoelectrodes for neural stimulation and functional scaffolds for tissue engineering). In order to understand the interactions of MWCNTs with the human body on a whole, it is important to know how they interact with the cells. In this study, we dispersed the MWCNTs with anionic surfactant, characterized the properties of dispersed MWCNTs, and then evaluated the uptake of MWCNTs by A549 lung epithelial cells using Confocal Raman spectroscopy.
