Graphene: Calling all chemists - pp10 - 11

Rod Ruoff

doi:10.1038/nnano.2007.432

Graphene has potentially useful electronic properties but it is difficult to produce and process on large scales. Working with chemically modified forms of graphene — such as graphene oxide — may provide an alternative.

Nanomedicine: Sizing up targets with nanoparticles - pp12 - 13

Rod Minchin

doi:10.1038/nnano.2007.433

Nanoparticles have many potential medical applications but their behaviour in the body is poorly understood. New studies in mice show that particles that don't have targeting molecules attached can selectively enter certain organs solely on the basis of their charge and size.

Christopher S. Chen

doi:10.1038/nnano.2007.431

Cell signalling that is normally biochemically regulated can now be stimulated, with reversible and external control, by attaching magnetic nanoparticles to a cell surface and applying a magnetic field.
