Colorimetric detection of target molecules with insensitivity to incident-light polarization has
attracted considerable attention in recent years. This resulted from the ability to provide rapid …

Possessing fantastic abilities to freely manipulate electromagnetic waves on an ultrathin
platform, metasurfaces have aroused intense interest in the academic circle. In this work, we …

We propose and numerically demonstrate high Q-factor sensors based on all-dielectric
metasurfaces, which are very sensitive to the change of the refractive index of the …

Symmetry‐protected quasi‐bound states in the continuum (BIC) controlled by metasurfaces
with broken in‐plane symmetry are widely exploited to achieve highly surface‐sensitive and …

A symmetric all-dielectric metasurface based on silicon and GaAs is proposed and
numerically studied. In the mid-infrared region, two Fano resonant peaks with a reflectance …

Sensing is a crucial step to provide information for biology and chemistry. The introduction of
a new method with high sensitivity, robustness and low cost has been a research hotspot …

Here, we indicate that metasurface-based biosensors consisting of silver-metasurface with
SiO2 and working in the near-infrared (NIR) spectral range can obtain simultaneous high …

Infrared plasmonic sensors offer enhanced biomolecule detection potential over visible
sensors due to unique spectral fingerprints, enhanced sensitivity, lower interference, and …

Metasurface provides a novel way to modulate light energy at specific wavelengths, namely
resonances, where there is a sharp drop in the transmission spectrum. Based on the …

Combining with the bound states in the continuum (BICs) theory in all-dielectric
metasurfaces has become an extensively used method to excite multiple high quality (Q) …
