Fig. 3. Application of complexes 2a–2h as luminescent probes for EGFR imaging in EGFR-overexpressing A431 human epidermoid carcinoma cells. Cells were treated with vehicle control (0.2% DMSO) or complexes 2a–2h (1 μM) containing 0.2% DMSO for 2 h before imaging. The luminescence intensity was detected at ex/em = 405 nm/500–700 nm. Scale bar = 50 μm.
