Description:
We report on the feasible generation of BiFeO 3 -Fe 3 O 4 Janus particles (JPs) based on droplet microfluidic method. Utilizing laminar flow and flow-focusing in microchannels, BiFeO 3 and Fe 3 O 4 nanoparticles were separately embedded in each hemisphere of one hydrogel particle. The size of the Janus particles showed favorable uniformity at micron scale and could be precisely controlled by flow rate regulation. The magnetism and ferroelectricity of the JPs were confirmed by magnetization and polarization measurements, indicating potential in multiferroic applications.
