Universidad de Zaragoza Engineering plasmonic nanostructures for label-free SERS detection of neurotoxic gases 2022 In this work, we explore the SERS based sensing capabilities of core-shell nanostructures for gas detection of neurotoxic agents at ppm level. 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 unit Access copy available to the general public Unrestricted info:eu-repo/grantAgreement/EC/H2020/823895/EU/SMART SENSING FOR RAPID RESPONSE TO CHEMICAL THREATS ON SOFT TARGETS/SENSOFT This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 823895-SENSOFT info: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/SERSing This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 883390-SERSing info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.224 2022 Electrical and Electronic Engineering 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Lafuente, M.
