Nanoparticle Characterization using Nanoparticle Tracking Analysis and Scanning Electron Microscopy. Particle size distributions for (a) blank NP (D10: 116.5 nm, D50: 170.6 nm, D90: 239.5 nm) and (b) NP-PPi (D10: 113.4 nm, D50: 184.2 nm, D90: 276.1 nm). Red error bars indicate ± 1 standard error of the mean from three separate nanoparticle tracking measurements. SEM representative images of (c) blank NPs and (d) NP-PPi in the dehydrated state.
