Over the past few decades, metal nanoparticles less than 100 nm in diameter have made a
substantial impact across diverse biomedical applications, such as diagnostic and medical …

Surface-enhanced Raman scattering (SERS) has become a powerful tool in chemical,
material and life sciences, owing to its intrinsic features (ie, fingerprint recognition …

Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

The advent of nanotechnology, and the need to understand the chemical composition at the
nanoscale, has stimulated the convergence of IR and Raman spectroscopy with scanning …

In this Review, the theory and applications of optical micro‐and nano‐resonators are
presented from the underlying concept of their natural resonances, the so‐called quasi …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Nanoscale localization of electromagnetic fields near metallic nanostructures underpins the
fundamentals and applications of plasmonics. The unavoidable energy loss from plasmon …

Titanium nitride (TiN) is one of the most well-established engineering materials nowadays.
TiN can overcome most of the drawbacks of palsmonic metals due to its high electron …

The nitrides of most of the group IVb-Vb-VIb transition metals (TiN, ZrN, HfN, VN, NbN, TaN,
MoN, WN) constitute the unique category of conductive ceramics. Having substantial …

Surface and interfaces play key roles in heterogeneous catalysis, electrochemistry and
photo (electro) chemistry. Tip-enhanced Raman spectroscopy (TERS) combines plasmon …
