Fabrication and Assembly of Magneto‐Responsive, Anisotropic, and Hybrid Microparticles of Variable Size and Shape

Abstract

Molded magnets: The co-assembly of silica colloids and iron oxide nanoparticles in a PDMS mold gives magnetic responsive microparticles. When dispersed in an aqueous solution (see picture), the microparticles could rotate and flip under the action of a magnetic field (1 kG). The particles could also be reversibly switched between aligned chain structures and a hexagonal array in both bulk solutions and in emulsion droplets.
