(A) The in vivo imaging of the mice, bearing BEL-7402, at different time after iv injection of DiR marked DOX&HAuNS-TSL. (B) The fluorescent imaging of various tissues at 6, 24, and 48h after the iv injection of the liposomes. (C) The accumulation of DOX&HAuNS-TSL in various tissues was calculated as %ID/g (the percentage of the injected dose per gram of tissue). The fluorescent intensity, responding the amount of the liposomes, was read by the imaging system. Inset: The accumulation of DOX&HAuNS-TSL in tumors at 6, 24, and 48 h.
