Triplets electrically turn on insulating lanthanide-doped nanoparticles

To turn on and obtain emission from lanthanide-doped insulating nanoparticles, an electrical excitation pathway coupling them to organic optical molecules to form nanohybrids is described, enabling tunable electroluminescence properties of LEDs fabricated from such materials.

Transient Au–Cl adlayers modulate the surface chemistry of gold nanoparticles during redox reactions

Controlling nanoscale interfaces is key for ensuring stable plasmonic and catalytic function yet remains difficult to achieve under operando conditions. Now it has been shown that transient Au–Cl adlayers function as redox-active Au(I) intermediates, modulating interfacial electrostatics. This modulation stabilizes gold nanogaps and directs ligand rebinding, thereby enabling reproducible regeneration of subnanometre architectures.

Single-molecule mid-infrared spectroscopy and detection through vibrationally assisted luminescence

Detecting the vibrations of individual molecules directly in the mid-infrared regime is hindered by thermal noise. Here researchers bypass conventional detectors and upconvert the mid-infrared photons into visible light using molecular bonds, yielding an optical readout for single-molecule vibrational spectroscopy.

Photoluminescence upconversion in monolayer WSe₂ activated by plasmonic cavities through resonant excitation of dark excitons

Here, the authors perform statistical measurements on hundreds of plasmonic nano-cavities embedding WSe₂ monolayers, and show the activation of anti-Stokes photoluminescence in WSe₂ through resonant excitation of a dark exciton at room temperature.

An integrative approach to reveal driver gene fusions from paired-end sequencing data in cancer

With a flood of cancer genome sequences expected soon, distinguishing 'driver' from 'passenger' mutations will be an important task. Wang et al. describe a bioinformatic method for identifying cancer-associated fusions and apply it to discover a recurrent rearrangement in lung cancer.

Giant mid-IR resonant coupling to molecular vibrations in sub-nm gaps of plasmonic multilayer metafilms

Short-range ordered plasmonic superlattices of Au nanoparticles have tunable infrared collective plasmon-polariton resonances. The enhanced molecule-plasmon interaction approaches the vibrational strong coupling regime, enabling molecular sensing through giant infrared absorption.
