a Fluorescence imaging of MDA-MB231 cell-bearing (right flank) and NIH3T3 cell-bearing (left flank) mice. b. Organ-distribution of nanoparticles 24h later. 1 × 10⁶ MDA-MB231 cells and NIH3T3 cells were implanted into the right flank and left flank of BALb/C nude mice (5 weeks, 20~25 g), respectively. Three weeks later, NIR-dye-conjugated HAssLG nanoparticles (10 mg/kg) were intravenously injected via the tail vein. The major organs of the mice were taken 24 h after nanoparticle administration
