Healthy challenges p451

doi:10.1038/nnano.2007.258

Medical applications of nanotechnology are growing, but a number of outstanding issues need to be resolved before nanomedicine moves from the lab to the bedside.

Subject term: Nanomedicine

Thesis

New materials, old challenges pp453 - 454

Richard Jones

doi:10.1038/nnano.2007.241

Nanotechnology could lead to materials that are stronger, lighter and stiffer. This is not a new claim but, as Richard Jones explains, it is an important one.

Atomic force microscopy: Getting a feeling for the nanoworld pp461 - 462

Robert W. Stark

doi:10.1038/nnano.2007.233

Nanoindentation probes can map the mechanical properties of surfaces and films with high resolution, but they are much slower than probes that image the topography. Now, a new atomic force microscopy technique can capture both pictures at once.

Nanomaterials: Diamondoids display their potential pp462 - 463

Neil D. Drummond

doi:10.1038/nnano.2007.232

Self-assembled monolayers of molecular diamonds on metal substrates have excellent electron-emission properties, bringing field-emission displays based on diamondoids a step closer to reality.

Block copolymers: Nanowire arrays build themselves pp464 - 465

Charles T. Black

doi:10.1038/nnano.2007.244

A combination of self-assembly techniques has been used to pattern ordered metallic nanowire arrays on silicon substrates in a versatile process that could prove useful for semiconductor electronics and sensing applications.
