REVIEWS
Microcantilevers vibrate in interesting, often
unanticipated ways. Understanding these phenomena can offer deep insight
into the physics of dynamic atomic force microscopy.
Arvind Raman et al.
A range of techniques can image magnetic domain
patterns. Two new techniques described here are able to sense long-range
magnetostatic interactions and probe short-range magnetic exchange
interactions.
Alexander Schwarz and Roland Wiesendanger
Highly selective protein adsorption and the ability
to reach subcellular locations means that nanoparticles can have an
impact on protein interactions and cellular behavior.
Iseult Lynch and Kenneth A. Dawson
There is much research on the toxicological and
environmental effects of direct and indirect exposure to nanomaterials,
but the results are contradictory.
Roberta Brayner
INSIGHT
Nanoscience and nanotechnologies are expected
to change our future so we need to start thinking about the associated
risks as well as the benefits.

COMMENT
Providing useful information to the consumer about
nano-related products presents a real dilemma to the nanotechnologist.

Read some accounts of nanotechnology risks, and
you might be forgiven for concluding that a single engineered nanoparticle
can kill you.
