✦ Synopsis

A 7-A resolution map of the purple membrane has been obtained by electron microscopy of tilted, unstained specimens. The protein in the membrane contains seven, closely packed, alpha-helical segments which extend roughly perpendicular to the plane of the membrane for most of its width. Lipid bilayer regions fill the spaces between the protein molecules.

By rotation of carbon nanotubcs about their long axis and obtaining images by high-resolution electron microscopy, it is shown that carbon nanotubes do not have a perfectly cylindrical shape especially near the ends of the tubes.
