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.
A magnetic resonance imaging probe that binds specifically to neurotoxic amyloid-beta oligomers can potentially be used for early detection of Alzheimer's disease.
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.
The stepwise stochastic motion of an individual organoarsenic(III) molecule along a linear track of thiols can be monitored in real time within a protein nanopore.
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.
A silicon-based photocathode with an epitaxial strontium titanate protection layer and a mesh-like nanostructured catalyst can provide an applied bias photon-to-current efficiency of 4.9% for water reduction.
Under continuous illumination, a non-symmetric axle-type molecule transits through a macrocycle only in one direction via a ratchet mechanism that rectifies Brownian motion.
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.
The systemic circulation time of adenosine is prolonged by forming nanoassemblies with squalene, and this can improve neurologic recovery in mice affected by a stroke or spinal cord injury.
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.
An array of interconnected nanobatteries templated in anodic aluminium oxide pores shows high capacity retention during fast cycling and excellent cyclability while operating at the maximum theoretical capacity of the storage material.
A sandwich assay labelled with gold nanoparticles can be mechanically and optically detected with the help of a silicon cantilever, allowing cancer biomarkers to be identified in serum at very low concentrations.
