VI Encontro Brasileiro de Espectroscopia Raman

In recent years, Raman spectroscopy intensified by surface phenomena (SERS) has emerged as a very promising methodology for the qualitative and quantitative determination of different substances, reaching low detection limits and simplifying sample pre-treatments. In this context, our group has developed flexible SERS platforms, based on silver nanoparticles immobilized in an agar gel, to be used in the in-situ determination of different molecules (for example pesticides and drugs).In this study we explore the possibility to detect cocaine in banknotes using the agar developed platforms and SERS spectroscopy.
