DLS spectra for the assessment of v- and ox- nPS/mPS sizes, suspended in maintenance cell medium (e.g. 2% SFC). The absence of aggregates due to protein interaction is clearly observable and all particles, both virgin and oxidized, show a normal distribution that was centered at 116.6 nm in v-nPS and at 160.7 nm in ox-nPS, while for v- and ox-mPS the values were 1,450 and 1,239 nm respectively.
