Fig. 1: Schematics of electron transfer-triggered imaging.
From: Electron transfer-triggered imaging of EGFR signaling activity
a Schematic of ETTE nanoprobe for electron transfer-triggered imaging (not to scale). b Time-resolved fluorescence curve of ETTE nanoprobes in water and in solution with glucose oxidase and glucose. The experiments were repeated independently three times. c Afterglow images of organs and tumors at 48 h after intravenous administration of ETTE nanoprobes without and with MutT homolog 1 (MTH1) siRNA as a therapeutic reagent, respectively. Tu tumor, Sp spleen, Li liver, Ki kidney, Lu lung, He heart. Color scale: 6.0 × 103–3.0 × 104.
