Abstract

The present invention relates to a nanostructure comprising a first hollow nanotube having at least one open end and a first anchor structure comprising a first anchor portion configured to anchor within the open end of the first nanotube, the first anchor structure further comprising a tether portion arranged to allow at least a part of said tether portion to extend outside of the end of the nanotube.
