The energy position of the van Hove singularity in a van der Waals flat-band system is detected by tunnelling (photo)currents within a field-effect structure.

Confocal optical microscopy is used to visualize—at high speed—solid (particle volume changes and phase-front velocities) and liquid electrolyte (concentration polarization gradients) dynamics inside operating batteries.

DNA-based point accumulation in nanoscale topography (DNA-PAINT) super-resolution imaging reveals the kinetics of the free energy of base-stacking interactions of all 16 dinucleotide combinations at the single-molecule level in patterned DNA-origami nanostructures.

A giant spin Hall effect with long spin diffusion length and coexisting with ferromagnetism is observed in AB-stacked MoTe₂/WSe₂ moiré hetero-bilayers.

DNA nanotechnology is used to develop fully synthetic, programmable and printable 3D cell-culture matrices with stress-relaxation crosslinkers that encode (nano)mechanical stability. The hydrogel performs on par with solubilized animal-basement-membrane-derived cell-culture matrices.

The observation of orbital currents with extended propagation lengths remains challenging. Here, Seifert et al. optically trigger ultrafast orbital currents in Ni|W|SiO₂ stacks that seemingly propagate ballistically with a giant decay length and low velocity.

Here the authors report on exoelectrogenic bacteria-derived membrane fusion-liposome-coated titanium dioxide nanoparticles to mimic extracellular electron transfer to enhance superoxide anion production under low-dose X-ray irradiation for radiodynamic therapy.

Here the authors report that the metabolome profile is an unexploited factor impacting the targeting efficacy and safety of nanomedicines, using cholesterol as an example, showing a way and need to develop personalized nanomedicines by harnessing disease-related metabolites.

A free-standing thin-film solid electrolyte (LiPON) shows remarkable mechanical flexibility and the ability to form uniform and dense lithium metal deposition for future solid-state batteries.

Evidence is provided for the formation of a collective state of short-lived excitons whose propagation resembles that of a classical liquid flows, with a speed reaching ~6% the speed of light.

In contrast to conventional thermal annealing approaches, the authors report on the self-assembly of complex mixtures of DNA at room or physiological temperature for generating user-defined programmable nanostructures capable of shape selection and transformation.

Spintronic nano-neurons and synapses can be connected by radiofrequency signals into neural networks that are capable of classifying real-world radiofrequency inputs without digitization at high speed and with low energy costs—an important step for artificial intelligence at the edge.

The development of flexible thermoelectrics is limited by the low power factor and brittleness of materials. Here the authors present strategy to turn Bi₂Te₃-based single crystals into flexible films with staggered-layer structure while maintaining superior thermoelectric performance.

Protein-based nanobiosensors with two epistatically interacting synthetic allosteric regulatory systems result in YES gate protein switches with large dynamic ranges and fast response times. These biosensors enable construction of rapid diagnostic tests compatible with clinical chemistry analysers.

Electro-osmosis in an anion-selective α-hemolysin nanopore is used to capture, unfold and transport polypeptides of over 1,200 residues, which allows the mapping of post-translational modifications in polypeptide chains by monitoring the ionic current at a single-molecule resolution.

A versatile electrokinetic trap overcomes rotational and translational Brownian motion for simultaneously controlling the two-dimensional position with a precision of up to 20 nm and 0.5° in the three-dimensional angle of an untethered nanowire under an optical microscope.

Using metal–organic chemical vapour deposition, high-crystallinity MoS₂ monolayers are grown directly on polymers and thin glass substrates at about 150 °C, thus avoiding any transfer process, preserving the electronic properties of MoS₂.

Overcoming the immunosuppressive tumour microenvironment is a challenge. A strategy to close the cancer–immunity cycle has been reported by integrating lipid nanoparticle–mRNA formulations and dendritic cell therapy to promote tumour elimination and develop antitumour immunity.

Signal amplification through hybridization chain reaction by targeting conserved regions of the M13mp18 bacteriophage-based scaffold sequences is used for in situ imaging of unlabelled DNA origami nanostructures.

Surface chemistry controls the location of WSe₂ nucleation on a stepped sapphire substrate. Preferential nucleation at either the top or bottom step edge can be used to minimize mirror twin domains and produce unidirectional WSe₂ monolayers.
