Physicists at the Georgia Institute of Technology have made important findings regarding gold on the nanoscale. They found that applying an electrical field on a surface-supported gold nanocluster changes its structure from a three-dimensional one to a planar flat structure. In another paper, they relate their discovery that gold in this size regime can be made magnetic through oxygenation of gold nanowires.

In November 2007, Which?, the UK consumer advocat group, commissioned a short survey among the general public which highlighted low levels of awareness for nanotechnologies and how they are being used. Following on from this, Which? undertook an additional research project with consumers - the Citizens' Panel on Nanotechnologies - which was published yesterday.
