The image depicts surface-emitting lasers consisting of a bulk nanocrystal layer covered by a 2D photonic crystal grating.

The cover shows an atomic force microscopy image of DNA origami after isothermal transformation from a rectangular to a triangular shape.

The cover image illustrates lithium intercalation channels between graphene and carbon-terminated SiC. The intercalation drives the motion of topological domain walls between different domains.

The cover depicts the controlled translocation of an individual molecule using a glass nanopore. Through the integration of nanopore sensing into a scanning ion conductance microscope, it is possible to control the translocation speed and detect single-nucleotide gaps.

The cover image shows a chamber of a microfluidic device where RNA from lysed viral particles (image left) is rapidly amplified through the action of both the RNA polymerase enzyme (image centre) and the injected electrons from the plasmonic materials (image bottom). The result obtained is both amplified DNA and the generation of protons, which drives the solution colour change towards yellow (image top).

The cover image is a microwave transmission measurement showing avoided crossing between a hole spin and a microwave photon in a silicon transistor. The observation is a hallmark for coherent quantum mechanical interactions and could be useful in quantum circuitry.

The cover shows a confocal fluorescence microscopy image of a tumour tissue section in the presence of genetically recombinant human ferritin nanocages. Ferritin nanocage particles permeate the tissue through the tumour vasculatures, here visible at individual blood vessels level.

The cover image represents a distribution of nonvolatile memory charge arrays on a potential energy surface landscape. Memory arrays based on surface potential engineering can execute nonlinear activation during the computing process, resulting in low power consumption.

The cover image depicts the continuous reflection of a light signal between a semi-transparent mirror and a nanostructured dielectric substrate. The optimized shape of the dielectric unit cell implements a matrix multiplication to the signal corresponding to the mathematical problem of interest.

The microscopy image shows a multi-micron DNA structure obtained from crisscross polymerization of thousands of uniquely addressable DNA-origami ‘slats’.

See Wintersinger et al.

The cover image depicts an isolated ion–water cluster inside a carbon nanotube. Such clusters are responsible for the unusually fast electrophoretic transport of potassium ions and lead to a strong breakdown of the Nernst–Einstein relation.

The cover shows two trapped nanoparticles whose motion has been simultaneously cooled through a technique that uses precise shaking of laser beams.
