• reproducibility. Furthermore, we demonstrate how the particle size can be changed from 5.2 ± 0.9 nm to 11.8 ± 1.7 nm by changing the reaction temperature and droplet residence time in the droplet capillary reactor. Keywords: capillary reactor; droplet synthesis; magnetic nanoparticles; narrow size distribution

• filled with water. Exact experimental parameters regarding the comparison between batch and droplet synthesis (Table S1, Table S2), the effect of temperature (Table S3), and the effect of residence time on particle size (Table S4) can be found in Supporting Information File 1. For batch synthesis

• droplet synthesis In theory, nanoparticle synthesis in droplets should result in reproducible nanoparticles with a narrow size distribution, compared to particles synthesized through conventional batch synthesis. To evaluate this statement, magnetic iron oxide nanoparticles were synthesized in a batch
