Nanotechnology and Drug Delivery

The current issue of Nature Drug Discovery contains a fascinating paper on the state of work in artificial viruses, in effect, a nanotech approach to gene-based therapies:

Nanotechnology is a rapidly expanding multidisciplinary field in which
highly sophisticated nanoscale devices are constructed from atoms,
molecules or (macro)molecular assemblies. In the field of gene
medicine, systems for delivering nucleic acids are being developed that
incorporate virus-like functions in a single nanoparticle. Although
their development is still in its infancy, it is expected that such
artificial viruses will have a great impact on the advancements of gene
therapeutics.
