Resumo

The possibility of creating an optical sensor based on carbon nanoparticles used to amplify the Raman signal is discussed. Carbon nanotubes or graphene flakes can be used as reinforcement. This possibility is confirmed by the results of an experiment demonstrating the signal enhancement effect (SERS) when using carbon nanotubes. The possibility of using graphene flakes for this purpose is confirmed by experimental results indicating the presence of plasmonic oscillations in these objects, necessary for the implementation of the SERS effect.
