Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.Abstract INTRODUCTION Astrocyte dysfunction is central to Alzheimer's disease (AD), yet expression patterns of astrocytic markers remain poorly defined. We measured Aquaporin‐4 (AQP4) and glial fibrillary acidic protein (GFAP) in post‐mortem frontal cortex of AD patients and controls across BrainNet Europe (BNE) stages.

Optical Manipulation of Whispering Gallery Mode Microlasers for Controlled Cellular Delivery
Advanced Optical Materials, Volume 14, Issue 28, 24 July 2026.Optically trapped whispering‑gallery microlasers are precisely positioned onto non‐phagocytic mammalian cells to report local refractive‑index changes in real time. Time‑dependent wavelength shifts reveal successive stages from membrane contact to internalization.

Single-mode silica microsphere Raman laser tunable in the U-band and beyond
Results in Physics, 2020 We demonstrate experimentally a silica microresonator-based single-mode Raman laser tunable in the U-band and beyond. The Stokes wavelength is tuned in the 1631–1685 nm range when tuning a C-band pump laser in the 1520–1570 nm range.

Aggregate, Volume 7, Issue 6, June 2026.The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.
