Fig. 3. (A–C) Nanoparticle size distribution based on TEM images. Bimodal size distribution can be observed for particles made with the combination of DCM with toluene solvent (3C). (D–F) Multi-angle LS results, where extrapolation q → 0 results in inverse z-average radii <Rh>1/z of 182, 163 and 308 nm for DCM, DCM + MeCN and DCM + toluene nanoparticles respectively. (G–I) CryoSEM images, here both fractions of particles are visible for particles made with DCM + toluene (cNP = 10 mg ml−1). Also, some larger particles could be found with samples made either with DCM only or with DCM + MeCN solvents.
