Two-dimensional magnetic resonance imaging of hydrogen in organic samples with a resolution of 12 nm can be achieved by using the spin of a nitrogen–vacancy centre in diamond as a sensor.
The spin dynamics of a nanomagnet assembled from three iron atoms can be tuned by atomic exchange coupling with the magnetic tip of a scanning tunnelling microscope.
A high-throughput nanosensor based on a gold nanoparticle and fluorescent proteins allows mechanisms of chemotherapeutic drugs to be screened in minutes, offering a tool for expediting research in drug discovery and toxicology.
Excitation transfer between nitrogen–vacancy centres and graphene can be used to detect the spin of the electron in the nitrogen–vacancy centre through electrical measurements.
The splitting of electron pairs, which is essential for electron-based quantum information processing, can now be obtained with electron pairs that have been generated on-demand.
Stiffness topography with sharp atomic force microscopy tips can be used to generate nanoscale cross-sections of nuclear pore complexes, and suggests that the selective barrier in the complexes consists of a crosslinked network of nuclear pore proteins.
Magnetic droplet solitons are shown to be stable excitations that can be controlled by applied magnetic fields and electrical currents in thin films with perpendicular magnetic anisotropy.
Magnetic excitations in a ferromagnet known as magnons can be converted into charge currents through a relativistic interaction that couples the spin of an electron with its orbital angular momentum.
The Stark effect can be used to address two qubits independently that are represented by semiconductor quantum dots, placed only a few nanometres apart.
Careful, low-noise measurement techniques allow record quality factors to be determined in ultraclean, suspended carbon nanotube resonators, which are comparable to those of much larger resonators.
Electrostatic force microscopy can directly observe charge flow along native protein nanofilaments that are used in bacterial respiration and cell-to-cell electron exchange.
A quantum bit that can be addressed with a gate voltage and has a very high control-fidelity can be realized in an electrically defined silicon quantum dot.
The coherent operation of individual 31P electron and nuclear spin qubits in a 28Si substrate shows new benchmark decoherence times and provides essential information on the dechorence mechanism.
The relationship between the electronic structure and the thermoelectric properties of molecular junctions is experimentally probed using a three-terminal device.
