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

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.

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.

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.
