SERS and electrochemical impedance spectroscopy immunoassay for carcinoembryonic antigen

This work describes an innovative dual detection approach, combining electrochemical and surface-enhanced Raman scattering (SERS) sequential readings, on the same sensing surface. This was achieved by establishing (i) an antibody binding stage on a suitably modified screen-printed electrode (Au-SPE)...
