Tiny robots—around 50 times smaller than the diameter of a human hair—open up fascinating possibilities: they enable the controlled manipulation of objects far too small for human hands. This brings us closer to a long-standing ...
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.
Just as an antenna interacts with radio waves, light interacts with metallic nanostructures. Therefore, understanding how a structure influences field oscillations provides valuable insights into the structure's physical ...
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. ...
Researchers at National Taiwan University have developed a tip-enhanced Raman spectroscopy platform that can identify tiny structural differences in oligosaccharides without fluorescent labels. The method can distinguish ...
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 ...
