Characterization of particles. A Fluorescence microscopy. B SEM. C Diameter analysis of SEM images. Dotted lines indicate diameters specified by the manufacturer. n.d. = not detectable. D DLS measurements of at least two samples and calculated values for hydrodynamic diameter and polydispersity index of 1:1000 diluted stock dispersions. E Zeta Potential of at least three samples of 1:1000 diluted stock dispersions. F Distribution of particles in hydrophilic (water) and lipophilic (octanol) phases after 0 h and 24 h incubation. Error bars indicate standard deviation of independent experiments (n = 3). G AF4 coupled to Multi Angle and Dynamic Light Scattering (MALS/DLS) H SAXS data of PMMA particles and a curve fit utilizing a log-normal size distribution of the diameters (left, black circles and red solid line, respectively). The intensity of the data around q = 0.5 nm− 1 decays with about q− 3 (indicated by arrow and a blue dotted line). Size distribution corresponding to the curve fit in the left-hand pane (right). Displayed is the partial differential function (PDF, red line) and cumulative distribution functions (CDF, black dashed line)
