Epidermal growth factor receptor (EGFR) is reported to promote solid tumor growth and, thus is relevant to multiple cancers and as a crucial indicator for the diagnosis of cancers.[48] Cetuximab (C225) is a human IgG1 monoclonal antibody that inhibits EGFR.[49] In 2017, Tang and coworkers reported the cetuximab conjugated AIE probe mAb–CSPP for wash‐free imaging.[50] mAb–CSPP showed almost no emission in normal cells but was highly emissive in specific cancer cells with EGFR overexpressed. Here, EGFR is linked to cancer.
