and capillaries have been suggested [30]. Through these advantages provided by microfluidicdroplet reactors, it should be possible to synthesize the particles with narrower size distributions and higher reproducibility compared to conventional batch synthesis [31]. In the specific case of the
nanoparticles inside of a microfluidicdroplet capillary reactor. Due to the advantages of this droplet capillary reactor, a narrower particle size distribution and higher reproducibility, compared to conventional batch synthesis, could be achieved. Furthermore, we demonstrated how the particle size could be
