Abstract

This communication describes an ultrafast high-sensitivity plasmonic-driven thermal sensing approach for the detection of tumoral markers. Gold nanoprisms derivatized with antibody against carcinoembryonic antigen (anti-CEA) are used to label CEA molecules and imprint thermal signals upon illumination, enabling sensitivities up to the attomolar range in real patient samples.
