An electric field gradient can be used to control spin qubits in silicon quantum dots, enabling switchable fast single-qubit gates and, potentially, scalability.

The transport of dissolved ions inside tiny carbon nanotubes apparently violates the famous Nernst–Einstein relation, which links diffusive and electric-field-driven motion.

Polymer-based nanomedicines have been engineered to ratiometrically deliver three different drugs to tumors, thereby bridging in vitro–in vivo correlation and producing synergistic therapeutic efficacy in multiple myeloma mouse models.

Nanosensors allow early detection of the onset and type of plant stress for a more precise and sustainable agriculture

A nanoscopically thin gold coating at the optical percolation threshold was fabricated using scalable methods. Despite its extreme thinness, the film absorbs about 30% of the solar radiation while being transparent. The resulting photoinduced heating prevents or mitigates fogging on transparent surfaces.

This Review illustrates opportunities for the nanophotonics community when adopting machine learning approaches.

Spin manipulation for quantum information processing often requires cost-intensive sample design and cryogenic temperatures. Now, surface functionalization of CsPbBr₃ quantum dots enables coherent optical manipulation of hole spins under ambient conditions.

High-performance all-electrical control is a prerequisite for scalable silicon quantum computing. The switchable interaction between spins and orbital motion of electrons in silicon quantum dots now enables the electrical control of a spin qubit with high fidelity and speed, without the need for integrating a micromagnet.

A transparent, 10-nm-thick gold film working at the percolation threshold provides superior antifogging capabilities.

Using an ultrafast high‐sensitivity centred dark-field imaging approach, the picosecond-scale evolution of intrananoparticle vibrations can be directly mapped with a spatial resolution down to 3 nm.

A graphdiyne-assisted ultrafast sparking synthesis platform is developed to synthesize a group of metastable nanomaterials, including single-atom materials, high-entropy alloys and high-entropy oxides.

A molecular catalyst supported on carbon nanotubes efficiently transforms the notorious water pollutant 1,2-dichloroethane into a useful chemical feedstock ethylene in an electrified membrane filtration device.

An antiviral and antibacterial cotton textile based on a fundamentally different principle of incorporating copper ions into the cotton structure at the atomic level is fabricated with excellent air/water retainability and superior mechanical stability.

K⁺ ions in sub-1-nm-diameter carbon nanotube pores are found to disobey the Nernst–Einstein relation by three orders of magnitude. This behaviour results from drastically different mechanisms for ion diffusion and electromigration inside these channels.

Although nanomedicine has shown benefits with respect to soluble drug administration, whether delivery of multiple drugs within the same nanocarrier has advantages over administration of single-drug nanomedicines or combination of free drugs at the same dosage is unclear. Here we use a bottlebrush prodrug platform to show that the delivery of three drugs in a synergistic combination in animal models outperforms other combinatorial approaches for multiple myeloma therapy.

Downregulation of specific proteins named scramblases might enhance tumour immunosuppression. In this paper the authors first show that the scramblase Xrk8 is overexpressed in tumour cells upon treatment with chemotherapeutics, and then develop a nanomedicine platform for co-delivery of a cancer prodrug and an siRNA directed against the Xrk8 gene, showing therapeutic effect and enhanced immune response in animal tumour models.

A non-destructive surface-enhanced-Raman-scattering-based nanoprobe detects multiple endogenous molecules in living plants that are released under either abiotic or biotic stress, indicating the possible onset of a disease.
