Nanophotonics, Volume 12, Issue 21, Page 4055-4062, October 2023., 2023 Abstract miRNAs are small non‐coding RNA molecules which serve as promising biomarkers due to their important roles in the development and progression of various cancer types. The detection of miRNAs is of vital importance to the early‐stage diagnostics and prognostics of multiple diseases.

Advanced Theory and Simulations, Volume 6, Issue 9, September 2023., 2023 The fundamental principle of Surface Plasmon Resonance (SPR) is the collective oscillation of electrons on the surface of a metal when illuminated with light of a specific wavelength. It offers high sensitivity, real‐time monitoring, label‐free detection, and the ability to analyze complex biological samples.

Enhancing angular photonic spin Hall effect at surface plasmon resonance. [PDF]
NanophotonicsAbstract The photonic spin Hall effect (PSHE) is the deep subwavelength spin component shift of light induced by the spin–orbit interaction of photons. Here, we demonstrate a polarimetric scheme to directly measure the surface plasmon resonance‐enhanced angular PSHE in the Kretschmann configuration using a gold film. In contrast to the weak measurement

The Interaction of 2D Materials With Circularly Polarized Light
Advanced Science, Volume 10, Issue 10, April 5, 2023., 2023 The interaction between 2D materials and circularly polarized light (CPL) provides an attractive control knob for investigating emergent exotic phenomena, especially for chiral‐electronics, photonics, and optoelectronics effects. This review summarizes exciting chiral light‐induced phenomena in representative 2DMs, covering from distinct interaction ...

Nanophotonics, Volume 12, Issue 7, Page 1271-1284, April 2023., 2023 Abstract This study theoretically demonstrated an insight for designing a novel tunable plasmonic biosensor, which was created by simply stacking a twisted bilayer graphene (TBG) superlattice onto a plasmonic gold thin film. To achieve ultrasensitive biosensing, the plasmonic biosensor was modulated by Goos–Hänchen (GH) shift.

Goos-Hänchen and Imbert-Fedorov shifts for the rotating elliptical Gaussian beams
Results in Physics, 2020 We introduce a theoretical research of the Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts for the rotating elliptical Gaussian beams (REGBs) incidencing on a weakly absorbing semi-infinite medium. We show that the rotation ellipse parameters a, b and c

Topological localized region of Goos-Hänchen shifts in reflection and transmission
Results in Physics, 2023 In this manuscript, the Goos-Hänchen shift of the transmitted and reflected probe beam is controlled and modified. Topologically localized regions are reported in the G-H shift by introducing the position and orbital angular momentum dependency in the ...

The tunnelling of electromagnetic radiation in chirped dielectric structure
EPJ Web of Conferences, 2017 The tunnelling of optical beams through chirped Bragg grating is considered. Lateral shifts of transmitted and reflected beams were calculated. The saturation of Goos-Hanchen shift of transmitted light beams is shown.
