Plasmonic-driven thermal sensing: ultralow detection of cancer markers

Chem Commun (Camb). 2013 May 7;49(35):3676-8. doi: 10.1039/c3cc39112d. Epub 2013 Mar 27.

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.
