Label‐Free Characterization of Lipid Interfaces Using Plasmonic Gold Nanorods as Optically Active Nanosensors

open access: yesAdvanced Optical Materials, EarlyView.
A label‐free plasmonic nanosensor platform is presented based on single gold nanorods for the nanometric characterization of lipid interfaces. By correlating optical scattering signals with membrane packing and refractive index, this approach enables the detection of gel‐to‐fluid transitions in lipid interfaces, offering a robust, high‐resolution ...

A sensitive genetic-based detection capability for Didymosphenia geminata [PDF]

open access: yes, 2006
It is now well recognized that the increase in global transportation over the last two decades has brought with it an increased potential for the introduction of unwanted microorganisms (aquatic or terrestrial) that may have drastic effects on human and ...

The Role of Porosity in SERS

open access: yesAdvanced Optical Materials, EarlyView.
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

CTAB genomic DNA-extraction v1

open access: yes, 2021
Protocol for the isolation of genomic DNA for a wide range of plant species. This protocol is based on a paper published by Aboul-Maaty et al. 2019 (https://doi.org/10.1186/s42269-019-0066-1). Comments have been added in bold in brackets. CTAB is used here to filter out phenolic compounds usually found in plant samples that cannot be removed otherwise.

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 ...
