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.

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.

Quantum biological electron transfer has potential in diagnostic and therapeutic settings. Here the authors report the triggered apoptosis of cancer cells using electricical input to wirelessly induce redox interactions at bio-nanoantennae in proximity to cancer cells.

Non-invasive monitoring of oxygen levels has implications in a wide range of applications. Here, the authors report that biological imaging beyond 1,500 nm enables in vivo quantitative assessment of oxyhaemoglobin saturation at vascular resolution with high sensitivity.

A transfer approach for monolayer MoS₂ using polypropylene carbonate shows a negligible residue coverage of ~0.08% and an ultralow Ohmic contact resistance of ~78 Ω µm, with an excellent on/off ratio of ~10¹¹ at 15 K.

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.

Nanotechnology is advancing at an accelerated pace in applications and novel nanomaterials. To become an enabling technology for a more sustainable society, we identify and assess nanomaterials and applications trends with potentially significant environmental implications.
