Advance online publication
Atomic force microscopy
Letter by Dong et al.The flexibility of biomolecules at the microsecond timescale can be monitored under physiologically relevant conditions and with high spatial resolution using a technique based on atomic force microscopy.
Advance online publication
Antimicrobial nanoparticles
Article by Liu et al.A class of core–shell nanoparticles self–assembled from amphiphilic peptides can kill a range of bacteria, yeast and fungus, and suppress bacterial growth in the brains of rabbits infected with meningitis.
Advance online publication
Nanotoxicology
Progress article by Dobrovolskaia et al.More and more drugs and diagnostics based on nanoparticles are being developed, but evaluating their immune response is challenging because traditional methods may not work. This article outlines practical recommendations for evaluation and the implications for regulation.
Advance online publication
NEMS mass spectrometry
Article by Naik et al.Mass detection of single biomolecules by a nanoelectromechanical system (NEMS) has been demonstrated. Precipitous frequency shifts, proportional to the mass of the molecules, are recorded in real time by the NEMS mass spectrometer as protein molecules and nanoparticles adsorb, one–by–one, onto an ultrahigh frequency nanoresonator.
Research Highlights
Optical transistors from single molecules, imaging magnetic nanoparticles at a distance, and insulating nanoislands in ferromagnetic gallium manganese arsenide.
Advance online publication
Nanomagnetism
Article by Ruotolo et al.A magnetic vortex can be made to gyrate by a d.c. spin–polarized current. The synchronization of four magnetic vortices has now been demonstrated in work that could lead to improved nanoscale microwave oscillators.
