To demonstrate the power of this automation, we carried out parameter screenings for 5 block copolymers for which the individual chain lengths and the nature of the hydrophobic and the hydrophilic block were varied, respectively, spanning over a minimum of 75 individual experiments per obtained 3D surface plot as shown in Figure . Already small changes in the system, even if only a 25% reduction in overall concentration of the polymer, can have profound effects on the obtainable size of a particle, which underpins why in previous work, data often could not be reproduced. Besides the fact that low overall flow rates tend to yield nanoaggregates with larger size, only few generalizations can be made at present. Future work will need to focus on more systematic variations of the polymer structure in order to understand the influences of individual block lengths on particle size. At present, even with more than 500 individual conditions screened (in triplicates), it is difficult to come to a more refined picture. Further, the parameter space was still relatively small with only 3 dimensions being covered. Obviously also salt content in the water phase, or for example temperature will have profound effects on the particle size.
