The automated screening of nanoparticles were performed for a specific block copolymer varying three different factors: total flow rate, water/polymer mixing ratio and concentration of the polymer solution. Generally, screening experiments were done at polymer concentrations 2 mg/mL, 5 mg/mL, 7.5 mg/mL and 10 mg/mL, starting with a 20 mg/mL stock concentration of the polymer. The dilution was done using neat THF solvent, where the mixing of polymer and solvent was done using the Y mixer. Total flow rates were varied over 1 ml/min, 2 ml/min, 4 ml/min, 6 ml/min and 8 ml/min. In the study of mixing profile changes, 90/10, 80/20, 70/30, 60/40 and 50/50 ratios of water/polymer were studied. Each experiment was generally triplicated, hence altogether performing 300 experiments per each block copolymer screening over this wide space of flow parameters and polymer concentrations. (4 concentrations x 5 flow rates x 5 mixing profiles x 3 replicates). All 300 experiments in consecution took about 36 hours to perform autonomously.
