Branched silver sensor offers more sensitive light-based drug measurements in blood plasma
Medications can save lives, yet for some drugs, the concentration in a patient's bloodstream determines whether a treatment is effective or whether harmful side effects may occur. Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, have de

New breakthrough spots deadly methanol without opening bottles
A new optical technique developed by researchers at the University of St Andrews and Adelaide University allows toxic methanol in alcoholic spirits to be detected without opening the bottle. Published in the Journal of Physics: Photonics, this new work offers a powerful new tool
New superconducting X-ray detector is up to 1,000 times more sensitive
A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin materials, nanostructures, and ul
Lithium-doped carbon nanorings show promise for next-generation optical devices
Nonlinear optical materials are essential for advanced photonics and laser technologies, but researchers are still searching for ways to optimize organic, carbon-based alternatives. Using computational modeling, scientists demonstrated that adding a lithium atom to the outside of
Physicists demonstrate Hong–Ou–Mandel interference with more than 10 atoms
Physicists demonstrate Hong–Ou–Mandel interference with more than 10 atoms
In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 indistinguishable neutral atoms—an effect that has been predominantly observed in photonic systems.
Layered ZnPS₃ emits single photons, opening new path for quantum chips
Scientists from the Faculty of Physics at the University of Warsaw, in collaboration with teams from the National University of Singapore and Radboud University in the Netherlands, have observed single-photon emission from layered two-dimensional material ZnPS₃. This discovery re
Plug-and-play single-photon source can work at room temperature
The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built into a compact 19-inch rack-mounted device that operates without cryogenic cooling. Designed as a plug-and-play system that works as soon as it is powered on,

Saturn-ring-like laser emission from chiral polymeric microspheres
Controlling light within microscopic spaces is crucial for next-generation optical devices such as photonic integrated circuits and localized sensors. Microspheres formed of luminescent π-conjugated polymers act as optical resonators that confine and amplify light via whispering
Researchers define new frontier in quantum materials
Researchers define new frontier in quantum materials
Researchers at City College of New York physicist Vinod M. Menon's Laboratory for Nano and Micro Photonics (LaNMP) have outlined an emerging frontier in quantum materials: atomically thin systems in which light, magnetism and electric charge are strongly intertwined. This rapidly

Fim do superaquecimento? Dispositivo controla calor sem gastar energia
Pesquisadores da Universidade Metropolitana de Osaka, no Japão, desenvolveram um dispositivo térmico inovador capaz de controlar a direção para onde o calor é irradiado e "lembrar" sua configuração de funcionamento mesmo após ser totalmente desligado da energia. A descoberta tem potencial de revolucionar a dissipação de calor em chips, principalmente os mais exigentes, como aqueles para data centers. Publicado na rev
