Nature Nanotechnology, Published online: 22 April 2024; doi:10.1038/s41565-024-01653-xA simple manipulation of an electrolyte’s glass transition enables nanoresolved electrochemical ion implantation doping in a variety of polymeric semiconductors.

Nature Nanotechnology, Published online: 19 April 2024; doi:10.1038/s41565-024-01650-0Plasmonic tunnel junctions integrated with a monolayer semiconductor are found to emit photons with energies exceeding the input electrical potential. This peculiar phenomenon is ascribed to being triggered by inelastic electron tunnelling dipoles inducing optically...

Nature Nanotechnology, Published online: 17 April 2024; doi:10.1038/s41565-024-01644-yA method for overcoming antibiotic resistance uses multimodal nanoparticles that target bacterial defence mechanisms while enhancing the innate immune response.

Nature Nanotechnology, Published online: 17 April 2024; doi:10.1038/s41565-024-01648-8Antimicrobial resistance is becoming more prevalent. Here the authors use multimodal nanoparticles to modulate the infected microenvironment, recruit neutrophils and alleviate hypoxia to restore neutrophil function, demonstrating therapeutic efficacy against MRSA infections...
