ERBB2 and cancer: The same group further conducted multiplextargeted in vivo cancer cell detection (Figure C) using three different tricarbocyaninederivatives (CyNAMLA-381, Cy7LA, Cy7.5LA). CyNAMLA-381- and Cy7LA-AuNPs were functionalized with antiepidermalgrowth factor receptor (anti-EGF) antibody for selective SERS imagingof oral squamous carcinoma cell (OSCC) and Cy7.5LA-AuNPs were conjugatedwith an anti-HER2 antibody as a negative control.
