• below 4.1 nm. Importantly, neutron reflectometry studies showed that the thickness of the hydration layer increases with the RPEG/D ratio, a geometric parameter now recognized as critical for predicting the in vivo fate of nanoparticles [15]. Pharmacokinetics data in the study further demonstrated that
