We recently demonstrated plasmonic supracolloidal chains by synthesizing gold and silver nanoparticles in the cores of diblock copolymer micelles. From spherical micelles having nanoparticles, we induced patchy micelles and assembled them into supracolloidal chains by adjusting the solvent polarity. In addition, by incorporation of preformed quantum dots in diblock copolymer micelles, fluorescent supracolloidal chains were achieved with the same protocol of patch and chain formation. In this presentation, we first synthesized magnetic nanoparticles such as cobalt and iron oxide for the purpose of magnetic supracolloidal chains. By the thermal decomposition method, nanoparticles with a narrow size distribution were obtained. Then, we incorporated these nanoparticles into the cores of diblock copolymer micelles in order to produce patchy micelles and their supracolloidal chains with nanoparticles. |
