The image on the cover shows a 3D-printed sculpture composed of nanoscale gyroid crystals in titania that exhibit optical chirality under visible light.

See Yang et al.

The cover shows a microscopy image of synthetic cells expressing artificial organelles, assembled from genetically encoded RNA nanostructures.

See Giacomo Fabrini et al.

The cover shows an image of water-based micro- and nanopatterned circuits obtained by using silk as a surfactant on a hydrophobic wafer.

See Omenetto

The image presents a topologically protected polariton emission formed by hybridizing optical and excitonic excitations in a halide perovskite microcavity.

See Kai Peng et al.

The cover shows an atomic force microscopy image of nanoscale doped plastic polymers achieved through precise electrochemical ion implantation.

See Lanyi Xiang et al.

The cover image illustrates the ferroelectric hysteresis loop in doubly aligned magic-angle bilayer graphene. Applying an electric field to this heterostructure injects electrons into the ferroelectric graphene system non-volatilely, enabling quasi-continuous switchable ferroelectric states. This ferroelectricity coexists with the Chern insulator effect, enabling the selective switching of topologically protected quantum edge states, which can support noise-immune neuromorphic computing applications.

The cover image depicts a coloured scanning electron microscopy image of a network of cortical neurons grown on a microelectrode array used for combined force and electrophysiological measurements.

See Muller et al.

The cover image depicts a flexible 10 × 10 matrix of narrow-band and high-efficiency green tandem light-emitting diodes, combining nanocrystal perovskite light-emitting diode and organic light-emitting diode units.

See Lee et al.

The cover image shows a three-dimensional reconstruction of a mouse bladder affected by a prominent tumour, with urease-powered nanobots targeting the tumour.

See Simó et al.

The cover image depicts the design of a DNA origami-based nanoturbine with a central axle connected to three blades arranged in a chiral configuration docked into a solid-state nanopore. Imaged by a single-molecule technique, the nanoturbine shows sustained rotation driven by a transmembrane electrochemical potential across the nanopore.

See Shi et al.

The cover image presents resistance maps of rhombohedral pentalayer graphene as a function of magnetic field and charge density. These maps provide evidence for correlation-driven Chern insulator states in a natural graphitic material. No moiré reconstruction is required.

See Han et al.

The cover image depicts the capturing of cellular membranes together with their native environment in the form of nanodiscs using amphipathic copolymers. Imaged by a single-molecule technique, the nanodiscs reveal the oligomeric distribution of membrane proteins.
