Nature Nanotechnology, Published online: 16 April 2024; doi:10.1038/s41565-024-01645-xA single-walled carbon nanotube spring stores three times more mechanical energy than a lithium-ion battery, while offering wide temperature stability and posing no explosion risk.

Nature Nanotechnology, Published online: 08 April 2024; doi:10.1038/s41565-024-01639-9A double-blind, randomized, controlled human exposure trial of highly purified and thin nanometre-sized graphene oxide nanosheets shows that acute inhalation of aerosolized nanoparticles is not associated with harmful effects in healthy humans.

Nature Nanotechnology, Published online: 03 April 2024; doi:10.1038/s41565-024-01641-1Engineering the tunability of protein assembly in response to pH changes within a narrow range is challenging. Here the authors report the de novo computational design of pH-responsive protein filaments that exhibit rapid, precise, tunable and reversible assembly and...

Nature Nanotechnology, Published online: 01 April 2024; doi:10.1038/s41565-024-01640-2How can light be efficiently manipulated below the single-pixel level? An answer is now provided using near-field interactions for nanopillars in a metasurface — phase gradients in the gaps between the nanopillars constitute a new degree of freedom that enables efficient...

Nature Nanotechnology, Published online: 01 April 2024; doi:10.1038/s41565-024-01636-yA metasurface consisting of merely four nanopillars at the wavelength scale is sufficient to generate a high-quality vortex beam.
