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.

ICMAB researchers from the NANOPTO group at ICMAB have recently published two studies demonstrating how cost-effective fabrication techniques can produce highly efficient chiral nanostructures with potential applications in sensors, imaging, and even quantum technologies.

The first study, published in Nature Communications, showcases self-assembled chiral plasmonic architectures (triskelion patterns) made from gold and silver nanoparticles. These structures demonstrate exceptional optical responses, selectively interacting with circularly polarized light, opening up exciting possibilities for advanced optoelectronic devices.
