These nanostructures generate intense localized surface plasmon resonances which are engineered by tuning geometrical parameters, in particular the aspect ratio of the metallic nanorods and the thickness of the silica mesoporous shell to extend the spectral window for the SERS based sensing from the visible to the near-infrared. This nanoarchitecture enables the integration of sampling preconcentration and detection of Sarin gas surrogate in a single SERS unit2022http://zaguan.unizar.es/record/12963910.1109/SENSORS52175.2022.9967361http://zaguan.unizar.es/record/129639oai:zaguan.unizar.es:129639info:eu-repo/grantAgreement/EC/H2020/823895/EU/SMART SENSING FOR RAPID RESPONSE TO CHEMICAL THREATS ON SOFT TARGETS/SENSOFTThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 823895-SENSOFTinfo:eu-repo/grantAgreement/EC/H2020/883390/EU/Advanced Surface Enhanced Raman Spectroscopy (SERS) based technologies for gas and liquids sensING in the area of chemical protection/SERSingThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 883390-SERSingProceedings of IEEE Sensors ...
