Conspectus Rational design of nanocrystals with high controllability via wet chemistry is of
critical importance in all areas of nanoscience and nanotechnology research. Specifically …

Multi‐layered plasmonic nanostructures are able to highly promote the near‐field
confinement and effectively activate analytes, which are of predominate significance but are …

In this Letter, a rational and stepwise method for the solution-phase synthesis of asymmetric
Au split nanorings by adopting Au nanoprisms as a template has been demonstrated. The …

Surface enhanced coherent anti-Stokes Raman scattering (SECARS) is a sensitive tool and
promising for single molecular detection and chemical selective imaging. However, the …

The fast label-free detection of specific antibodies and their concentration in blood plasma is
useful for many applications, eg, in Covid-19 patients. The change in biophysical properties …

The effects of shape, size, and surface plasmon resonance (SPR) peak position (λSPR) on
nonlinear absorption (NLA) were investigated at 808 nm, using a femtosecond laser. We …

In this paper, we propose an all-dielectric metamaterials structure which contains four
asymmetric square holes in the unit cell to design a high-sensitivity refractive index sensor in …

In recent years, sensing structures based on Fano resonances have become a hot research
topic. In this study, a coupled structure, composed of a metal baffle metal-insulator-metal …

In this study, an all-dielectric metasurface is proposed, whose unit cell is composed of a
silicon elliptical disk and a silicon elliptical ring. The transmission of the structure were …

A sharp plasmonic Fano resonance is found to appear in a silver nanorod pair structure with
broken length symmetry. It is shown that it arises from strong interference between a narrow …
