This Review analyses the mechanisms of light extraction from perovskite light-emitting diodes and suggests new approaches towards ultrahigh electroluminescence efficiencies.

This Review discusses the latest theoretical progress related to exceptional points in non-Hermitian physics and the associated implications for emerging technologies in nanophotonics.

This Review highlights the role of transition metal dichalcogenides, hexagonal boron nitride and stacked heterostructures in applications in quantum communication, computation, sensing and single-photon detection.

This Review presents the most recent ferroelectric materials with wurtzite structure and emphasizes applications in memory and storage-based microelectronic hardware.

A novel ZrO₂-based photoresist enables an additive manufacturing printing speed of 7.77 m s^–1, with 38 nm resolution.

A reagentless, wireless, wearable aptamer nanobiosensor interfaced with a gold nanoparticle-MXene-based electrode enables the selective, automatic and non-invasive analysis of the female hormone oestradiol in sweat during menstrual cycles with subpicomolar sensitivity.

This study establishes a method for multiplexed detection of up to 40 different biomarkers in a single assay by combining nanopore sequencing with analyte-selective barcoded probes, including cardiac disease-associated microRNA directly from blood serum.

Biosynthesis of magnetosomes is of interest for a range of applications. Here, factors needed for magnetosome biosynthesis are evaluated and new diverse bacteria are engineered to biofabricate magnetic nanoparticles, facilitating translation to biotechnology and nanomedicine.

Here, the authors find a decrease in hepatic phagocytic uptake of nanoparticles in old mice due to age-associated downregulation of the scavenger receptor MARCO, which led to improved tumour delivery and antitumour efficacy of cancer nanomedicine, showing the need to consider age as a factor in therapeutics.

Nanoparticle penetration into tumours is an obstacle to cancer therapeutics. Here the authors show that the tumour vascular basement membrane constitutes a barrier that reduces nanoparticle delivery and demonstrate an immune-driven strategy to overcome the barrier, increasing nanoparticle movement into tumours.

As researchers, developers, policymakers and others grapple with navigating socially beneficial advanced technology transitions — especially those associated with artificial intelligence, DNA-based technologies, and quantum technologies — there are valuable lessons to be drawn from nanotechnology. These lessons underscore an urgent need to foster collaboration, engagement and partnerships across disciplines and sectors, together with bringing together people, communities, and organizations with diverse expertise, as they work together to realize the long-term benefits of transformative technologies.

The largest nanoscience and nanotechnology conference in the world took place again after a four-year hiatus.

Reducing cancer-related deaths can only happen with a better understanding of cancer biology and the development of improved, new therapeutics and delivery mechanisms. Nearly all cancer research is dependent upon the models being used, the model’s accuracy, and appropriate validation and benchmarking. Here the need for such considerations is discussed in line with the goal of the Cancer Moonshot.

Ultrathin ferroelectric materials, including perovskites, hafnium oxides, and van der Waals stacks are of increasing interest because they exhibit properties that are hard to achieve in bulk and because of their suitability for low-power miniaturized devices.

Recycling plastics waste into value-added chemicals using efficient and selective novel nanocatalysts promises economic as well as environmental benefits.

Graphene, transition-metal dichalcogenides, MXenes and the other members of the flatland family are becoming a rich playground for chemists, enlarging the range of applications these nanomaterials can be used for.
