Microfluidic synthesis and characterization of SMMF. (A) The photograph showing the microfluidic device used in this study, with a U.S. five cent coin for scale. (B) Simulation results demonstrating mixing at a flow rate of 4mL/min in microfluidic spiral channel, where two flows having different concentrations achieve complete mixing within about one run (see details in SI). (C-F) SEM image of hierarchical silica microflower at different magnifications. (G) and (H) showing TEM images of the as-synthesized silica microflower and FeCo-doped silica-magnetic microflower, respectively. (I) SEM image of SMMF (a) and the corresponding EDS elemental mapping analysis showing the presence of O (b), Si (c), Fe (d), and Co (e).
