Lateral fluorescence imaging of mice bearing MDA-MB-231 tumors. MDA-MB-231 tumor-bearing mice were i.v. injected with Apt-QLs (a) or QLs (b) (15 mg lipid/kg), and in vivo fluorescence images were acquired by the Maestro imaging system at various time points. The background auto-fluorescence was pseudo-colored as green, and the Q-dot signal is indicated by red. Upper panels, grayscale images; lower panels, unmixed fluorescence images.
