Nanotechnology is intimately intertwined with efforts to bring bottom-up synthetic cell research to the forefront, and only strengthening these bonds will expand the scope of what this might achieve.

An aptamer-based nanobiosensor has been integrated into a wearable sweat sensor, allowing non-invasive tracking of the female reproductive hormone, oestradiol, with the potential to deliver sustainable solutions to female reproductive healthcare needs.

In regenerative medicine, stem-cell-derived extracellular vesicles are emerging as cell-free nanotherapeutics. Here, the authors show that coating these nanovesicles with blood proteins such as albumin improves their uptake by liver cells, offering a better treatment strategy for liver diseases.

A transition metal/carbon nanocomposite material has been designed for positive electrodes in Li||S batteries. It enables Li||S batteries to be fast charged–discharged in <5 min, which represents a breakthrough in the development of high-power Li||S batteries.

Assessment of the health risks of exposure to anthropogenic nanomaterials is crucial to maximize their potential applications. This double-blind, randomized controlled study in healthy humans evaluates the impact of inhalation of graphene oxide nanosheets on acute pulmonary and cardiovascular functions.

Here the authors present a non-FRET DNA-templated silver nanocluster probe that exhibits a distinct colour switch from green to red upon nuclease digestion, visible under UV excitation, offering a low-cost, effective alternative to fluorescent reporters for detecting nuclease activities.

Distinguishing proteoforms and post-translational modifications has remained a challenge. Here the authors explore single-molecule fluorescence resonance energy transfer to probe amino acids via DNA exchange and map the location of individual amino acids and post-translational modifications within single full-length protein molecules.

Scientists encounter pressure to validate their research work, leading to varied benchmarks and methods for performance assessment in the broad energy research field. Interlaboratory studies help highlight discrepancies in reported figures of merit, underscoring the need for standardized protocols, transparent reporting, and detailed analysis for fair comparisons. Here, we discuss this topic, focusing on battery materials.

An encodable DNA clutch with the ability to recognize microenvironmental molecular inputs intelligently complements the remote control of a 200-nm sized magnetic nanomachine. This nanomachine interacts with biological machinery in vitro when the encoded clutch selectively engages the engine with the rotor while external magnetic fields power the rotation.

A robust initialization protocol has been demonstrated for a four-qubit nuclear spin register in silicon. The protocol, driven electrically through electric-dipole spin resonance, enables high-fidelity qubit control and hence a route to a register-based quantum computer that exploits the exceptional coherence properties of atom qubits in silicon.

An electric dipole spin resonance protocol making use of hyperfine interaction enacts high-fidelity initialization of a four-qubit nuclear spin register in silicon. This protocol allows for high-fidelity qubit control and a path towards a register-based quantum computer using the exceptional coherence properties of donors in silicon.

The nanospace confinement of a magnetic nanoparticle within a porous cage, coupled with an encodable DNA clutch interface, enables a remotely powered and controlled rotary nanomotor that is autoresponsive to its microenvironment.

An intelligent meta-imager can perform multi-channel convolutions to accelerate machine vision for incoherent light.

The legal definition of a nanomaterial differs around the world, meaning that the same material may be classified as a nanomaterial, or not, depending on the country where it is classified. The first steps towards converging on an international definition are to recognize the differences between existing nanomaterial definitions and to agree on particle counting methods. Meanwhile, we propose a naming convention that indicates the key criteria of a specific definition of a nanomaterial.

Synchronized dynamics of quantum dot ensembles are essential for the generation of giant optical responses. To this end, coherent electronic coupling in quantum dot solids induces cooperative enhancement of nonlinear optoelectronic responses.

A novel scanning single-electron charging spectroscopy enables nanometre-scale imaging of quasiparticle excitations and thermodynamic gaps in generalized Wigner crystals.

This Review highlights the current understanding of mechanisms underlying the mechanical changes occurring in diseased and immune cells and discusses new approaches to leverage and target biomechanical cues for immune engineering at various length scales for therapeutic interventions.
