Polyamine Polyamine concentration used for nanoparticle formation (µM) Diffusion coefficient (cm2/s) Hydrodynamic radius (nm)a
3-4-3 (Spermine) 25 2.4 × 10–8 94.6 ± 1.6
3-3-3 25 2.5 × 10–8 91.8 ± 5.3
3-3-3-3 5 2.8 × 10–8 80 ± 10.4
3-3-3-3-3 2 3.4 × 10–8 67 ± 6.4
3-4-3-4-3 2 4.5 × 10–8 51 ± 1.6

aAll measurements were made in 10 mM Na cacodylate buffer with the indicated concentrations of polyamines. Data given are mean ± S.E.M. of 3–5 separate measurements.
