Nanoparticle hollowing method promises medical advances

Abstract:
A process to "carve" highly complicated shapes into nanoparticles has been unveiled by a team of researchers.

It involves a chemical process which hollows out the particles into shapes such as double-walled boxes and multi-chambered tubes.

The researchers said this would aid the creation of more complex nano-objects.

They said these could ultimately be used to revolutionise medical tests and aid drugs treatments.
Ion attack

The research was carried out by the Catalan Institute of Nanotechnology in Bellaterra, Spain and is published in the latest issue of Science.

To deliver their results the scientists refined a series of existing corrosion techniques including the "galvanic effect".
