Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew ...
Recent advancements in nanophotonics are moving beyond isotropic noble metals to achieve dynamic and directional control over plasmons. Conventional localized surface plasmon resonances (LSPR) are limited by their isotropic ...
Argonne and Northwestern University scientists teamed up to understand how light interacts with metallic nanoframes, with implications for biosensing, quantum information science and beyond.
Scientists have created the first microlasers capable of detecting individual molecules and even single atomic ions, a breakthrough that could significantly advance early disease diagnosis and molecular-scale medical testing. ...
Diagnosing some diseases could be as easy as breathing into a tube. MIT engineers have developed a test to detect disease-related compounds in a patient's breath. The new test could provide a faster way to diagnose pneumonia ...
A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on a centimeter-sized chip, ...
Researchers have found a way to use solar energy to power a key chemical reaction that drives many manufacturing industries. This new method can significantly reduce the energy required to run these operations, eliminate ...
Adjusting the size and chemistry of nanocrystals within an ultrathin surface can speed up light-driven chemical reactions, according to a University of Michigan Engineering study published in the Journal of the American Chemical ...
The global development of civilization diseases is a challenge that requires many modern solutions, not only in terms of treatment, but first and foremost in terms of early diagnostics. One of the highly sensitive methods ...
You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, while X-rays reveal its internal structures and infrared captures a material's radiating heat. ...
