Chiral plasmonic nanostructures push the limits of light manipulation on the nanoscale

Molecules in a Twist: How a Flash of Light Flips Chirality

Scientists in Japan have uncovered a surprising twist, literally, in how molecules organize themselves. By introducing tiny leftover fragments from previous assemblies, they discovered a way to flip the direction of helical molecular structures. Using specific intensities of UV and visible light, they controlled whether these molecules formed left-handed or right-handed spirals, revealing a new [...]

Chiral plasmonic nanostructures push the limits of light manipulation on the nanoscale

Researchers from ICMAB are revolutionizing how we manipulate light at the nanoscale using chiral plasmonic structures—nanomaterials designed to interact with polarized light in extraordinary ways.
