From theoretical model to experimental realization, the bound state in the continuum (BIC) is
an emerging area of research interest in the last decade. In the initial years, well-established …

Biosensors have been designed and developed for detecting biomarkers, biomolecules,
proteins, enzymes, organisms, and various types of bacterial and viral diseases since the …

Non-radiative bound states in the continuum (BICs) allow construction of resonant cavities
with confined electromagnetic energy and high-quality (Q) factors. However, the sharp …

A quasi-bound state in the continuum (QBIC) has unique attraction in optical switch,
nonlinearity, communication, and sensing due to its ultrahigh radiation quality (Q) factor. The …

Advanced sensing devices, highly sensitive, and reliable in detecting ultralow
concentrations of circulating biomarkers, are extremely desirable and hold great promise for …

Symmetry-protected bound states in the continuum (SP-BICs) are one of the most intensively
studied BICs. Typically, SP-BICs must be converted into quasi-BICs (QBICs) by breaking the …

An important topic of modern nanophotonics focuses on the bound states in the continuum
(BIC) that the non-radiative localized waves lie within the radiative continuous spectrum …

An ultra-sensitive THz metasensor is presented based on quasi-BIC Fano resonance, which
can distinguish extremely dilute concentrations (nM) of solutions. It provides a …

Localized surface plasmon resonances (LSPRs) in metallic nanostructures attract great
attention for their potential applications such as highly sensitive optical sensors. However …
