La spettroscopia Raman potenziata da superfici (SERS) sfrutta la risonanza plasmonica localizzata (LSPR), regolata dalla condizione di Frohlich per l'amplificazione del segnale ottenuta tramite risonanze plasmoniche in nanoparticelle metalliche. Questo meccanismo è impiegato in biomedicina attraverso approcci label-free e label-based (con strutture ingegnerizzate) per la diagnosi e il monitoraggio di patologie. Di particolare rilevanza sono le nanostrutture d'oro, favorite per la loro stabilità e funzionalizzate con agenti di targeting per mirare selettivamente biomarcatori nel sangue. Le prospettive future si concentrano sull'integrazione con l'Intelligenza Artificiale per la creazione di dispositivi portatili con l'obiettivo di trasformare il SERS in uno strumento clinico rapido e affidabile.

Abstract
Surface-enhanced Raman spectroscopy (SERS) exploits localized surface plasmon resonance (LSPR), tuned by the Frohlich condition, for signal amplification obtained through plasmonic resonances in metallic nanoparticles. This mechanism is used in biomedicine through label-free and label-based approaches (with engineered structures) for the diagnosis and monitoring of diseases. Gold nanostructures are particularly significant, favored for their stability and functionalized with targeting agents to selectively target biomarkers in the blood. Future prospects focus on integration with Artificial Intelligence for the creation of portable devices with the aim of transforming SERS into a rapid and reliable clinical tool.| File | Dimensione | Formato | |
