Carbon nanotubes (CNT) are thought to lead to novel types of nanomedicines. In our laboratories, CNT were made compatible to physiological environments after functionalization by the 1,3-dipolar cycloaddition reaction. This has allowed their exploration as a platform to construct delivery systems for drugs and nucleic acids in vitro and in vivo. The interaction between cells and CNT is a critical issue that will determine any future biological application of such structures. In this communication we will show that various types of functionalized carbon nanotubes (f-CNT) exhibited a capacity to be uptaken by a wide range of cells (prokaryotic and eukaryotic) and can intracellularly traffick through different cellular barriers. Moreover, we will present the great potential offered by water-soluble f-CNT as new vectors for delivery of plasmid DNA to cells and organs. The mechanisms by which f-CNT are able to cross cell membranes and deliver their cargo will also be discussed. Energy-independent mechanisms are explained based on the cylindrical shape and high aspect ratio of f-CNT that can allow their penetration through the plasma membrane, similar to a ‘nanosyringe’. | | ISBN: | 978-1-4200-8504-4 |
