A study of the magnetic fine structure of the electronic states in a semiconductor quantum dot coupled to a superconducting contact highlights important elements that should be taken into account in the search for Majorana modes in the solid state.
A solid-state nanopore can be integrated with a graphene nanoribbon transistor to create a sensor that can detect DNA molecules using both the ionic current and the electrical current in the graphene nanoribbon.
Low-power visible light can be used to manipulate the surface charge of solid-state nanopores and can be used to control the translocation dynamics of DNA and proteins.
Efficient photocurrent generation, which can be tuned by the electric field of a gate to reach both high external and internal quantum efficiencies, is shown to occur in vertical heterostructures comprising graphene, MoS2 and metals.
The nucleation of single skyrmions in magnetic nanostructures and their spin transfer-induced motion in the presence of defects are investigated by micromagnetic simulations.
Surface plasmons are adiabatically focused at the interface between a metallic nanotip and a semiconductor surface to establish a new type of nanoscopy using hot electrons.
Nanoparticles with plasmonic, magnetic, catalytic and luminescent properties can be self-assembled into heterogeneous superlattices with the help of DNA.
Single-walled carbon nanotubes can target tumours in a two-step approach in which nanotubes modified with morpholino oligonucleotide sequences bind to cancer cells that have been pre-targeted with antibodies modified with oligonucleotide strands complementary to those on the nanotubes.
The magnetic exchange interaction at buried interfaces between magnetic and non-magnetic materials can be probed by investigating the interaction of spin-polarized electrons with magnon modes in the ferromagnetic layer.
Quantitative label-free snapshot proteomics can be used to obtain time-resolved profiles of human plasma corona formed on silica and polystyrene nanoparticles, and shows that rapid corona formation affects early nanoparticle pathophysiology.
Micromagnetic simulations describe both the current-induced motion of skyrmions in nanostripes and the nucleation of single skyrmions by spin-polarized currents.
Three-dimensional films — comprising polymeric phases of different molecular weights and compositions — are arranged in complex hierarchical patterns and used for wafer-scale patterning.
The chemical properties of a molecular monolayer on the surface of a non-spherical nanoparticle depend on its local curvature; an effect that can be exploited to drive the self-assembly of these nanoparticles into different structures.
The solution–liquid–solid process is carried out in a microfluidic reactor to support the continuous synthesis of semiconductor nanowires in solution.
