Over the years, researchers have been exploring ways to artificially design chiral structures
and materials, namely metamaterials and metasurfaces. They exhibit unique optical …

The excitation of surface-phonon-polariton (SPhP) modes in polar dielectric crystals and the
associated new developments in the field of SPhPs are reviewed. The emphasis of this work …

The highest possible resolution for printed colour images is determined by the diffraction
limit of visible light. To achieve this limit, individual colour elements (or pixels) with a pitch of …

Post‐pandemic era poses an imperative demand on progressive sensing devices whose
performance largely relies on the morphologies and structures of sensing materials. Despite …

Surface enhanced Raman spectroscopy (SERS) is a powerful technique for sensitive
analysis which is attracting great attention in the last decades. In this review, different gold …

Demand for accessible and affordable healthcare for infectious and chronic diseases
present significant challenges for providing high-value and effective healthcare. Traditional …

Chirality describes mirror symmetry breaking in geometric structures or certain physical
quantities. The interaction between chiral structure and chiral light provides a rich collection …

We present reflective plasmonic colors based on the concept of localized surface plasmon
resonances (LSPR) for plastic consumer products. In particular, we bridge the widely …

In this review, the weightiest decadal developments of surface-enhanced Raman scattering
(SERS) and nanoplasmonic materials in sensing applications are discussed. Today, there …

Plasmonics provides great promise for nanophotonic applications. However, the high optical
losses inherent in metal-based plasmonic systems have limited progress. Thus, it is critical …
