  • Persistent luminescence is a promising bioimaging technique that is not affected by background autofluorescence, but its in vivo application is challenged by the fact that the materials currently available are activated by high-energy light, with emission in the ultraviolet and visible spectral windows. In this paper the authors engineer X-ray activated, lanthanide-based nanoparticles with a tunable emission in the biologically relevant NIR-II spectral region, which allows high-contrast, multimodal in vivo deep-tissue organ imaging.

  • Among the candidates for large-scale quantum computing devices, silicon-based spin qubits offer an outstanding nanofabrication capability for scaling-up. In an array of three spin qubits in silicon, high-fidelity state preparation and control enable the creation of a three-qubit Greenberger–Horne–Zeilinger state with 88% state fidelity.

    Analysis
    • This Review presents the emerging understanding of the importance of the dynamic and evolving protein corona composition in mediating the fate, transport and biological identity of nanomaterials in the environment. Principles specific to the environment are presented, along with a perspective on next steps toward mechanistic and predictive insights for the next phase of eco-corona studies.

  • The FAIR principles provide compelling guidelines on how to achieve reusability of nanotechnology data.

    Editorial
  • The challenge of assessing the scope and magnitude of risk from nanomaterials is urgent for society and ignoring risks could be detrimental for development. This challenge is bigger than the individual capacities on each side of the Atlantic, but effective cross-Atlantic collaboration can solve essential riddles about the use of nanomaterials.
