Table 1. NIRF copy number per PZn3-based vesicle, reported as a function of polymersome size for a 5 mol% membrane loading.

Polymersome size Example No. of copies of NIRF
Small (<300 nm) 100 nm 2,500
Medium (300 nm-1 μm) 500 nm 75,000
Giant (>1μm) 1 μm 300,000

Computations assume a 1-nm2 projected area per PBD block composing the polymersome's bilayer membrane (31).
