Suitably Functionalised Gold Nanoparticles as Heavy Metals Sensors Transducers Based on Carbonic Anhydras

The interesting properties of gold nanoparticles (AuNPs) have stimulated their increasing applications in various research fields such as nanotechnology, materials science, and sensing. To this purpose the immobilization of gold nanoparticles on suitable transducers surfaces is still under study. Aim of this work was to optimize the adhesion and distribution of colloidal gold nanoparticles on glass substrates suitable to generate a nanostructured plasmonic transducer for sensing application.
