Under full computer control, the parameter space in the nanoparticle flow synthesis is systematically screened, and DLS results are obtained automatically. The devised software collects all data and summarizes the results for the user in a continuously updated graphical interface. As we will show below, this approach allows for in-depth investigations into the particularities of nanoaggregate formation, and synthesis outcomes can be mapped in detail for a series of polymers that we have subjected to this screening.
