nanotubes readily enter cells

This is one of the few good nanotube projects that I have heard of. It shows that nanotubes with chemical modifications on their surfaces can readily enter cells. With that said, I think that nanotubes are a fantastic tool for research but perhaps are too often the focus of research. Magnetic beads are equally exciting, but do not carry the nanotechnology label and thus can not become a standalone force in science. They are viewed as a useful new tool for separating biological molecules but not a field of study.
