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.
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.
Addressable DNA structures with lateral dimensions of ~2 µm can be self-assembled starting from over 1,000 distinct DNA-origami monomers via joint capture of the non-nearest neighbours.
Measuring the in situ activation status of T cells is important to gauge the efficacy of immunotherapy approaches. In this Article the authors design a chemical probe that binds to the T cell membrane and scavenges reactive oxygen species (ROS), preventing ROS-driven T cell exhaustion while serving as a magnetic resonance imaging probe to quantify T cell activity in tumours and predict radiotherapy outcomes.
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.
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.
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.
Scanning near-field optical microscopy measurements show that polaritonic nanophotonics is attainable in natural low-symmetry materials, leading to a general way to manipulate light at the nanoscale.
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.
Living systems employ a common set of building blocks that can self-organize into a multitude of different structures. Now, a model system based on programmed non-reciprocal interactions, which generically emerge in non-equilibrium systems with chemical activity, exhibits self-assembly pathways that feature temporal structures in the form of cyclic motifs.
A plasmonic metasurface for full-colour nanopainting simultaneously achieves a chiaroscuro presentation, wide-gamut palette, high saturation and dynamic colour tunability.
Accumulation of visceral fat, linked to adipocyte expansion and overgrowth, is the most detrimental aspect of obesity, and a major cause of obesity comorbidities. We develop a cationic nanomedicine based on polyamidoamine dendrimers that specifically targets visceral fat and shrinks adipocytes, inhibiting diet-induced obesity and improving metabolic health in murine models.
An optical signal transduction pathway through feedback-controlled homeostatic temperature oscillations and mechanoresponse enables dynamic functionalities in a hydrogel.
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.
Solid tumours are less responsive to immunotherapies than haematological tumours due to specific biological differences. In this paper the authors propose a strategy to decorate the cell membrane of solid tumours with a protein typically present on haematological tumour cells that promotes phagocytosis of cancer cells, and show that this results in an increased immunotherapy efficacy in animal models of solid tumours.
