Random two-dimensional arrays of carbon nanotubes, which are self-assembled via ion-exchange chemistry, can be used to create cryptographic keys by determining the connection yield and switching type of the nanotube devices.
In addition to reducing protein adsorption, modifying polymer nanocarriers with poly(ethylene glycol) or poly(ethyl ethylene phosphate) can alter the type and amount of plasma proteins that do get adsorbed, offering new insights on how the stealth effect is defined.
Focusing plasmon polaritons at the apex of a nanometre tip leads to the generation of an intense third-order nonlinear response used as a local probe for ultrafast nanoimaging.
Placing a single solid-state spin in an optical nanocavity results in a switch that operates at the fundamental quantum limit, where the spin modulates the polarization of a photon and a single photon flips the spin state.
Metal cations can form coordination complexes with the lone pair electrons of 2D metal chalcogenides, offering a potentially general strategy to surface functionalization.
Hybrid membranes made from protein amyloid fibrils and activated porous carbon can be used to remove heavy metal ions and radioactive waste from water.
Magnetic skyrmions can be stabilized at room temperature in cobalt layers sandwiched between heavy metal layers due to engineering of the interfacial Dzyaloshinskii–Moriya interaction.
Conductance oscillations periodic in Fermi energy and in magnetic flux measured in topological insulator nanoribbons reveal characteristic topological transport with quantized topological surface state subbands.
A photoactivatable nanoliposome carrying multikinase inhibitors tackles tumours by killing cancer cells through photodynamic therapy and simultaneously shutting down signalling pathways that allow cancerous cells to metastasize and escape treatment, offering a way to maximize the therapeutic efficacy of each treatment cycle.
π–π stacking and metal coordination allows the fluorescence properties of a tryptophan–phenylalanine dipeptide to be tuned from ultraviolet to visible as they self-assemble into nanoparticles, offering a durable and biocompatible imaging probe.
The spin transfer-induced resonant expulsion of the vortex core in magnetic tunnel junctions forms the basis of a novel integrated high-frequency threshold detector.
Electric field control of spin–orbit torque and magnetization switching can be achieved in a Cr-doped topological insulator thin film incorporated in a field-effect transistor structure, promising gate-controlled spintronic applications.
