Gold nanorods (NRs), pseudo-one-dimensional rod-shaped nanoparticles (NPs), have
become one of the burgeoning materials in the recent years due to their anisotropic shape …

Optical chiral imaging, as an important tool in chemical and biological analysis, has recently
undergone a revolution with the development of chiral metamaterials and metasurfaces …

The chiral state of light plays a vital role in light–matter interactions and the consequent
revolution of nanophotonic devices and advanced modern chiroptics. As the light–matter …

Surface lattice resonances (SLRs) are the coherent collective interactions between
periodically arranged nanoparticles, which are generally considered to be formed by the …

Chiral optical responses of bilayer metasurfaces made of twisted metallic nanorods are
investigated in detail with focus on the collective effect due to lattice resonance (LR). Using …

We suggest a plasmonic nanodevice for performing the second-order spatial derivative of
light fields. The device consists of five gold nanorods arranged to evanescently couple to …

Molecular recognition, which is key to the correct functioning of most biological processes, is
based on chiral entities fitting into and onto each other. Consequently, the concept of …

Chiral molecules that do not superimpose on their mirror images are the foundation of all life
forms on earth. Chiral molecules exhibit chiroptical responses, ie, they have different …

The effects of Fano resonance on the optical chirality of planar plasmonic nanodevices in
the visible wavelength range are experimentally observed and theoretically explained. The …

Optical activity is an effect of prominent importance in stereochemistry, analytical chemistry,
metamaterials, spin photonics, and astrobiology, but is naturally minuscule. Metallic …
