FIGURE 1.

(A) Fluorescence microscopy images of different-sized polystyrene particles (25, 50, 250, and 700 nm) in zebrafish embryos (13). (B) Maximum-intensity-projection PET/CT images of mice at 6, 12, 24, and 48 h after administration of [89Zr]Zr-desferrioxamine-polystyrene (20 nm; 1.85 MBq; 0.1 mg) via oral gavage (16). (C) Maximum-intensity-projection PET/CT images of mice at 1, 6, 12, 24, and 48 h after oral administration of [64Cu]Cu-DOTA-polystyrene (200 nm; 4.81 MBq; 57.8 μg) (17). %ID = percent injected dose; hpf = hours postfertilization.
