Time course of the mass delivered dose as a percentage of the administered dose for a monodisperse population (cyan) and a polydisperse population (orange) of (a) PEG nanoparticles, (b) PHPMA nanoparticles, (c) PMA nanoparticles. Parameters used are (a) μ = 186.55 nm, σ = 0.31, ρ = 1.13 g cm⁻³, (b) μ = 227.75 nm, σ = 0.36, ρ = 1.29 g cm⁻³, (c) μ = 186.69 nm, σ = 0.41, ρ = 1.33 g cm⁻³. (Online version in colour.)
