Unraveling the Role of Surfactants in Micelle‐Templated Growth of Chiral Plasmonic Nanoparticles

open access: yesAdvanced Optical Materials, EarlyView.
Micelle template‐directed growth enables precise control over the chiroptical properties of gold nanorods. Comparison of surfactants with varying aliphatic tail lengths shows that longer tails increase groove inclination and reduce groove density. Optimized conditions for the longest‐tail surfactant (C18) yield slightly higher g‐factors than those ...

Evolution of Collective, Radiative Plasmon Coupling in Confined, Soft Colloidal Films

open access: yesAdvanced Optical Materials, EarlyView.
Plasmon resonance coupling is continuously monitored during the uniaxial manipulation of a 2‐dimensional soft colloidal film containing hexagonally arranged spherical gold nanocrystals. This is realized by the in situ spectroscopic investigation of a monolayer of plasmonic core‐shell microgels confined at the air/water interface that is compressed in a

Applications of QSPR and Machine Learning in Molecular Photonics

open access: yesAdvanced Optical Materials, EarlyView.
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides

Dual‐Modality Detection of Intracellular Nanoparticles via Smart Polymer‐Enhanced SERS and Hyperspectral Microscopy Detection

open access: yesAdvanced Optical Materials, EarlyView.
Dual‐imaging strategy for PAP‐functionalized gold nanoparticles (PAP@Gold NPs) in HeLa cells. Fast screening is achieved via hyperspectral microscopy based on light reflection to track nanoparticle localization. Accurate detection is performed through SERS microscopy, leveraging the plasmonic enhancement of the PAP polymer signal for precise location ...
