From: IR808@MnO nano-near infrared fluorescent dye’s diagnostic value for malignant pleural effusion
To further optimize the dose and time, 2 × 106 A549 cells were chosen to incubate with IR-808@MnO at the final concentrations of 1 μl, 2 μl, 5 μl, 10 μl, and 20 μl for 30 min (A), and time points of 5 min, 10 min, 30 min, 1 h, and 12 h at 5 μl (B). The images obtained by staining with IR-808@MnO are shown. The average radiant efficiency values under different conditions were statistically analyzed. All images were acquired by an NIR fluorescence small animal live imager
