A supramolecular FRET signal amplification nanoprobe for high contrast and synchronous in situ imaging of cell surface receptor homodimers/heterodimers

The supramolecular nanoprobe could not only be activated by tumor cells and tissues to achieve high-contrast imaging of EGFR/EGFR and EGFR/HER2 dimers, but also successfully distinguish tumor cells and tissues from normal cells and tissues.
