Photoactivated QDs Kill Antibiotic-Resistant ‘Superbugs’
A technique for treating bacterial infections has successfully used light-activated quantum dots (QDs) to kill multiple multidrug-resistant strains. The QDs — which are inactive in darkness — were tailored to target particular infections thanks to their light-activated properties. The researchers said that by modifying the wavelength of light applied, they could activate the QDs to alter and kill infected cells with specificity.

Standard Heatsinks Efficiently Cool Plasmonic Components
Self-heating of active plasmonics, which limits achievable optical gain, has been a barrier to the development of optoelectronic microprocessors for high-speed data transfer. As the semiconductor industry looks to replace electrons with photons to increase data-transfer capabilities, they must also address the challenge of scaling down photonic components.

NIR-Activated Nanoparticle Therapy Suppresses Tumors
A nanoparticle drug-delivery system that combines photodynamic and molecular therapies has been shown to suppress tumor progress and metastatic outgrowth in animal models. The complementary treatment could improve outcomes and mitigate toxicity for patients with pancreatic cancer and other treatment-resistant tumors.

EUV Laser Enables Nanoscale 3D Imaging of Cells
A mass-spectral imaging system that integrates an EUV laser has enabled the mapping of cellular compositions in 3D, allowing researchers to watch how cells respond to medications at the nanoscale. The instrument comprises mass-spectral imaging technology and an extreme ultraviolet (EUV) laser. The EUV beam produces in a tiny stream of plasma that is very hot and dense, and which acts as a gain medium for generating EUV laser pulses.
