A one-step spin-coating approach to fabricate scalable epitaxial heterodimensional tin perovskite thin films results in near-infrared tin perovskite LEDs with a peak external quantum efficiency of 11.6%.

Protein degradation is a powerful tool for a range of applications and therapies. Here, a selective autophagy receptor mimetic against mutant p53 protein is developed to substantially elevate autophagy levels and to recognize and transport mutant proteins for autophagy-mediated degradation and anticancer effect.

Bidirectional neural interface electronic devices offer therapeutic options. Here, the authors present wafer-scale fabrication of flexible nanoporous graphene-based implantable microelectrode arrays with low impedance and high charge injection for in vivo brain recording and nerve stimulation.

Cytokine interleukin-12 (IL-12) has potential for tumour suppression yet off-target effects limit potential applications. Here the authors report on the delivery of IL-12 mRNA encapsulated in extracellular vesicles to lungs via inhalation and demonstrate the immunotherapeutic potential of targeted cytokine mRNA therapy.

High-density transparent microelectrode arrays with platinum-nanoparticle deposited and interlayer-doped double-layer graphene enable multimodal optical and electrical recordings with high spatiotemporal resolution to decode neural dynamics at different cortical layers from surface potentials.

Pre-adsorption of water molecules on a material surface, followed by assembly of a van der Waals (vdW) structure, provides a vdW water gap with a height that can be precisely tuned through variation of the amount of water adsorbed at the interface. This approach is applicable to different two-dimensional and even three-dimensional homo- and heterojunctions.

A metasurface-based approach is used to implement computationally expensive digital convolution operations in high-speed, low-power optics for improving the latency and power consumption of machine vision systems.

By preadsorption of water molecules on a material surface, a controllable ångström-scale van der Waals (vdW) gap is created, which can be applied to other vdW material systems with controllable gaps.

Nanofibre lung injury has previously been linked to the leakage of reactive oxygen and nitrogen species in frustrated phagocytosis. Here the authors use a nanosensor to demonstrate, map and track the generation of reactive species during the frustrated phagocytosis of model glass nanofibres.

Here, 3D nanofabrication and elasticity programming of monolithic soft microrobots equipped with magnetic springs with strain response at piconewton forces capable of deformation on micrometre length scales is demonstrated for applications in cell force sensing, cell manipulation and soft actuation.

The Review discusses the state-of-the-art polymer nanocomposites from three key aspects: dipole activity, breakdown resistance and heat tolerance for capacitive energy storage applications.

Chitosan/glucose co-polymers encapsulating silver sulfide quantum dots can be used to improve oral delivery of insulin in different animal models without hypoglycaemic incidents.

An atomically thin indium tin oxide film in the form of a quantum well exhibits a χ² of ~1,800 pm V^–1. Theoretical calculations point to an asymmetric electronic interband transition resonance as the reason for this large χ² value.

Insulin injections are not ideal and have an increased risk of hypoglycaemia. A preferable oral formulation based on silver sulfide quantum dots coated with a chitosan/glucose polymer is discussed, which has controlled insulin release and reduced risk of hypoglycaemia, and demonstrates applications in rodent and non-human primate models.

Organic and inorganic nanoparticles have different clearance mechanisms from the brain resulting in different biological fates and retention times.

Nanoparticle clearance is critical for safety and therapeutic applicability. Here the authors report the modulatory role of microglial extracellular vesicles on the brain clearance of organic and inorganic nanoparticles and provide a strategy to control their intracerebral fate.

Electrochemical carbon dioxide (CO₂) reduction in acid with a nano-structured tandem catalyst achieves high single-pass conversion efficiency and selectivity to useful C–C coupled products, bringing the process closer to commercial viability.

Nanoparticles naturally accumulate in the liver; this can be a major limitation to any therapy needing delivery to other organs or tissues. Here the authors review the reason for predominant liver uptake and explore different strategies used to target non-viral gene delivery nanoparticles to other organs and tissues.

Conserved regions of the circular DNA sequence of the M13mp18 bacteriophage, which is used as a scaffold for DNA origami construction, are targeted with specific hybridization-chain-reaction probes. The probes enable sensitive detection of DNA origami nanostructures in cells, organoids and tissues to assess their biodistribution and stability.

Using fluorinated elastomers in the fabrication of soft neural probes is shown to enhance spatiotemporal recording capability at single-neuron resolution within the central nervous system of rodents. Other soft encapsulation materials could be similarly engineered for high-resolution, long-lasting bioelectronics.
