Synthesis of iron oxide nanoparticles in a microfluidic device: preliminary results in a coaxial flow millichannel

A millimetric coaxial flow device operating under laminar flow has been designed to study the synthesis of iron oxide nanoparticles in a millichannel where the flow rate of the different reagents has been adjusted all over the experiments so that the magnetic and stable colloidal iron oxide particles with a size less than 7 nm have been prepared continuously.
