Despite graphene's apparent potential for anti-corrosion coatings, it is cathodic to most metals and can promote corrosion at exposed graphene–metal interfaces. This may accelerate dangerous localized corrosion that can seriously weaken the coated metals.

Two independent methods using near-field coupling to surface plasmon polaritons and magnetic brightening allow the observation of dark excitons in WSe₂.

A superlattice of gold nanoparticles shows stable lasing at different frequencies.

Hollow, nanoscale metal filaments in open-mesh architectures provide soft, shape-conformal electrical interfaces to the skin as the basis for high-precision, irritation-free sensing platforms.

Nanoparticles that capture antigens produced in situ by tumours induce the 'abscopal' effect, improving the treatment of distant cancer lesions.

Fast and scalable molecular logic circuits have been constructed by spatially localizing DNA hairpins on DNA origami scaffolds.

This review covers recent advances in nanoparticle and nanoscaffolding systems for the treatment of ischemic cardiomyopathy with emphasis on regenerative medicine, cell therapy and drug delivery technologies.

Near-field coupling to surface plasmon polaritons enables the observation of spin-forbidden dark excitonic states in monolayer WSe₂.

High-performance, CMOS-compatible ring-oscillators based on carbon nanotubes are fabricated by scalable and fully manufacturable processes.

A blue shift in the surface plasmon resonance of an indium tin oxide layer is observed—and electrically tuned—where a classical description would predict a red shift.

Scanning ultrafast electron microscopy provides new insights into hot carrier dynamics in amorphous semiconductors.

Nanoparticles can be utilized to capture tumour antigens and improve their presentation, which in turn improves the efficacy of cancer immunotherapy.

Magnetic brightening enables direct observation of spin-forbidden dark excitons in a monolayer WSe₂.

Arrays of nanoparticles grouped into microscale arrays support multiple nanolasing modes that can be tailored by changing the geometry of the superlattice.
