Gold nanoparticles can be assembled into ordered arrays through the site-selective deposition of mesoscopic DNA origami onto lithographically patterned substrates and the precise binding of gold nanocrystals to each DNA structure.
An atomic force microscope can probe both the surface and subsurface regions of a sample by exploiting nanomechanical coupling between the probe and the sample.
Nanoparticles can be assembled into superlattices and dimer clusters using a reconfigurable DNA device that also allows interparticle distances to be modified, post-assembly, in response to molecular stimuli.
A biosensor containing a microfluidic purification chip that supplies a downstream nanoribbon-detector can detect disease biomarkers in samples of whole blood.
A single dopant atom can dominate the subthreshold behaviour of a field-effect transistor, and this effect is enhanced if the atom is located near a dielectric.
Direct observations of domain walls and flux distributions in manganite have shed new light on the dynamics of the ferromagnetic phase in colossal magnetoresistance.
Electrically induced light emission from an individual carbon nanotube p–n diode is both more efficient and has a narrower spectrum than previously demonstrated, allowing emission from free and localized excitons to be identified.
Circulating tumour cells can be captured in the bloodstream by magnetic nanoparticles, and the use of gold-plated carbon nanotubes as a photoacoustic imaging agent allows multiplexed in vivo detection of these cells.
The phase diagram of single-walled carbon nanotubes in superacids is reported, including true solutions, which are suitable for processing into aligned nanomaterials.
The motion of a nanomechanical oscillator has been measured with ultrahigh precision using a microwave interferometer that operates close to the shot-noise limit.
Nanoparticles functionalized with ligands that target tumours can be cleared from the body through the kidneys if they have a hydrodynamic diameter of less than 5.5 nm.
Large arrays of aligned aromatic peptide nanotubes can be fabricated using vapour deposition methods, and used for energy storage and microfluidic devices.
Field-effect transistors made from graphene act as photodetectors at frequencies up to 40 GHz, demonstrating the advantage offered by graphene for photonic applications.
Semiconductor quantum dots grown by droplet epitaxy have been characterized with atomic resolution using direct X-ray methods, showing a core–shell structure with a composition that is strongly influenced by the substrate.
