Optical Metasurfaces for the Next‐Generation Biosensing and Bioimaging

open access: yesLaser &Photonics Reviews, Volume 19, Issue 10, May 22, 2025.
Recent advances in this understanding of light‐matter interactions, combined with innovations in the design and fabrication of large‐scale nanostructured metasurfaces, have enabled transformative approaches to biosensing and bioimaging. This review explores innovations in refractometric sensing, surface‐enhanced spectroscopy, and super‐resolution ...

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Channel Orthogonalization in Panel-Based LIS [PDF]

open access: yesarXiv
Large intelligent surface (LIS) has gained momentum as a potential 6G-enabling technology that expands the benefits of massive multiple-input multiple-output (MIMO). On the other hand, orthogonal space-division multiplexing (OSDM) may give a promising direction for efficient exploitation of the spatial resources, analogous as what is achieved with ...

Dual‐Band Metasurface‐Based Structured Light Generations for Futuristic Communication Applications

open access: yesSmall Science, Volume 5, Issue 5, May 2025.
This study introduces a single‐cell‐driven dual‐band metasurface platform generating nondiffracting perfect vortex beams for Ultraviolet–Visible wavelengths. The metasurfaces, composed of silicon nitride nanoantennas, maintain high transmission efficiency across dual spectrums.
