Dynamic Chiral Plasmonic Systems‐Based on Spiropyran Derivatives and Gold Nanorods
Advanced Materials Interfaces, Volume 12, Issue 23, December 8, 2025.Soft chiral plasmonic nanocomposites are prepared by embedding gold nanorods into spiropyran‐based supramolecular gels. The system self‐assembles into helical structures, enabling plasmonic circular dichroism. When illuminated with UV light spiropyran–merocyanine isomerization occurs, inducing reversible nanoscale reorganization and modulation of the ...

Advanced Optical Materials, Volume 13, Issue 34, December 2, 2025.This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Intracellular Monitoring of Luminescent Ag2S Nanoparticles in Fibroblasts
Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.This study investigates the long‐term luminescence behavior of Ag2S quantum dots (AS QDs) with three surface ligands (DTDTPA, 11MUA, PEG) in fibroblasts over 9 days. AS‐PEG showed stable uptake and enhanced NIR‐II emission, while others decreased due to oxidative stress.

Near‐Infrared Lifetime Nanothermometry Detects Microwave‐Induced Brain Heating
Advanced Optical Materials, Volume 13, Issue 36, December 19, 2025.Ag2S near‐infrared lifetime nanothermometers enable remote, minimally invasive readout of absolute brain temperature in vivo during telecommunication‐grade 3 GHz microwave exposure. Temperature‐dependent luminescence decay tracks real‐time heating in deep tissue, revealing rises approaching 4 °C and allowing systematic assessment of exposure parameters,

Commemorating the life and work of Rachel Carson
Agricultural &Environmental Letters, Volume 10, Issue 2, December 2025.Abstract Where the low tides reveal the shoals, Rachel Carson translated nature into written words. The sea was her focus until dying songbirds diverted her attention, resulting in Silent Spring. While her previous writings met with critical acclaim, the change to environmental concerns drew appreciation from the general population and hostility from ...
