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.
Graphene–MoS2 hybrid structures show potential for optical memory devices because of their high photodetection sensitivity, and their persistent photoconductivity that can be tuned by a gate voltage.
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.
Individual grain boundaries are imaged using a scanning plasmon interferometry technique, revealing mechanistic insights on electronic transport and plasmon propagation in graphene.
Circulating tumour cells from patients with early-stage cancers have now been captured and characterized by using functionalized graphene oxide nanosheets.
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.
Electromigration is used to rearrange single atoms in an atomic-sized metal contact and to switch its conductance between two well-defined values, enabling memory device functionality.
Bright luminescence from upconversion nanocrystals can be achieved by combining high-excitation irradiance with a high activator concentration. The enhanced brightness allows a single nanocrystal to be tracked, which can be used in bioimaging applications, for example.
