News</A>: Tiny "nanotubes" that assemble themselves using the same chemistry as
DNA could be ideal for creating better artificial joints and other body
implants. Researchers at Purdue University, the University of Alberta and
Canada's National Institute for Nanotechnology have discovered that bone cells
called osteoblasts attach better to nanotube-coated titanium than they do to
conventional titanium used to make artificial joints. <BR>"We have demonstrated
the same improved bone-cell adhesion with other materials, but these nanotubes
are especially promising for biomedical applications because we'll probably be
able to tailor them for specific parts of the body," said Thomas Webster, an
assistant professor of biomedical engineering at Purdue.</DIV></BODY></HTML>
