Scanning electron microscopy (SEM) image of an array formed by 45 nm colloidal Au nanoparticles self-assembled into chiral motifs, in this case triskelions, fabricated using a template-assisted ...

Cost-effective chiral nanostructures enable precise light control at the nanoscale, advancing applications in sensing, imaging, and emerging quantum technologies. (Nanowerk News) Researchers from ...

Chiral metasurfaces are ultrathin, two-dimensional assemblies of subwavelength resonators whose lack of mirror symmetry gives rise to strong differential responses to left- and right-handed circularly ...

Subscribe to our newsletter for the latest sci-tech news updates. Imagine trying to wear a left-handed glove on your right hand: It doesn't fit because left and right hands are mirror images that ...

(a) Electric field of LCP and superchiral light. (b) (Left) Schematic illustrating the generation of superchiral fields by focusing twisted RP beams. (Right) Theoretical model used to calculate the ...

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 ...

A terahertz platform built on an achiral gradient metasurface resolves the components, handedness, and mixing ratios of chiral biomolecule mixtures in a single broadband measurement. (Nanowerk ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...
