Plasmonic nanostructures for selective virus detection.

The study of novel plasmonic nanopatterns are of great interest for different applications including biological investigation and sensing. In this presentation we report some biosensing platforms designed, fabricated and characterized in the frame of the projects "SERSCov-Advanced Nanobiosensing platforms for diagnostics and POC surveillance" funded by POR Campania FESR 2014/2020 (CUP B53C22003100002) and "H2OSafety-Design and development of environmental sensors for the research of microbiological and chemical contaminants hazardous to health" funded by the National Fund Sviluppo e Coesione (FSC) Proof of Concepts projects (POC01\_00109). We tested the LSPR and SERS performances analyzing different viruses such as SARS-CoV-2, rotavirus and norovirus. Our results suggest that the considered plasmonic nanopatterns are promising for the development of devices for rapid, label-free and high-sensitivity detection of biological analytes and, moreover, they can be integrated with other on-chip chemical/biological devices to realize portable points-care-tools.
