Janus nanoparticles (JNPs) are unique building blocks which have asymmetric structures. Typical silver nanoparticles which are spherical shapes, for example, are composed of silver themselves and surface is homogeneous. However, JNPs are formed by heterogeneous surface; half of side is different from another side. They have been attracted and studied because of their different chemical or physical properties. For instance, their asymmetry give chiral properties. When we synthesis JNPs using magnetic nanoparticles (MNPs), they are able to be arrayed in magnetic field. Asymmetry and magnetic properties offer efficient and distinctive methods to target complex self-assembled materials. Here, we made Janus magnetic nanoparticles with Fe3O4. We coated half of surface with gold through sputtering followed by coordination of M13 bacteriophages and made them be arrayed by magnetic field. JNPs we made seem shuttlecock shapes. |
