Capillary droplet reactor for the synthesis of magnetic ironoxide nanoparticles

초록

Nanoparticles have gained large interest in a number of different fields due to their unique properties. However, it is still a challenge to obtain monodispersed, reproducible particles on typical lab scales. Here we present a microfluidic, capillary droplet for the synthesis of magnetic ironoxide nanoparticles. Compared to conventional batch synthesis the particles synthesized in our droplet reactor have a narrower size distribution and a higher reproducibility. Furthermore, we demonstrate how the particle size can be controlled from 5.2 ± 0.9 nm to 11.8 ± 1.7 nm by changing the reaction temperature and droplet residence time in the reactor. © © (2018) by Chemical and Biological Microsystems Society.
