The properties of core–shell nanoparticles can be tuned so that they efficiently convert radiation into heat, leading to therapeutic results that are competitive with commercial drug treatments.
It is possible to detect single viruses and single nanoparticles in air and in water by measuring how they change the output of a whispering-gallery-mode microlaser.
Covalently attaching nuclear pore proteins to solid-state nanopores forms a complex that can selectively transport certain proteins, similar to the nuclear pore complex.
Patterned metal and dielectric layers can be printed onto rigid or flexible substrates with high throughput to produce large-area metamaterials with negative index of refraction.
Ferromagnetic resonance is used to characterize nanoscale magnets with uniform magnetization profiles, by generating the driving field in the probed magnet itself.
Electrostatic doping of KTaO3 with an electric double-layer transistor has allowed superconductivity to be observed in this material for the first time.
Narrow subradiant plasmons supported by scalable, two-dimensional arrays of strongly coupled gold nanoparticles can be tuned by adjusting the nanoparticle height.
Most mechanical resonators operate in a linear damping regime, but the behaviour of nanotube and graphene resonators is best described by a model with nonlinear damping.
The orientation, spin coherence times and spin energy levels of individual nanodiamond nitrogen-vacancy centres have been measured inside living human cells with nanoscale precision.
It is possible to form covalent bonds between the gold atoms in an electrode and the carbon atoms in the backbone of a conducting molecule to create highly conducting contacts.
Arrays of cadmium selenide nanocrystals capped with molecular metal chalcogenide complexes exhibit high values of electron mobility and photoconductivity.
Single-electron transistors are written at the heterointerface of two oxides using an atomic force microscope tip, and the electrons in the device can be controlled by gating and the ferroelectric state of the heterostructure.
The temperatures of the graphene–metal contacts in working transistors have been measured with a resolution of ∼10 nm, revealing the presence of both heating and cooling effects.
Ultrathin large-area solid-oxide membranes can be fabricated using lithographically patterned metallic grids and used to make fuel cells that operate at relatively low temperatures.
Self-assembled nanostructured cathodes allow lithium-ion and nickel-metal hydride batteries to charge and discharge at very high rates without significant loss of capacity.
