Abstract
The controlled assembly of complex structures from simple colloidal building blocks can produce materials with properties useful in photonics, as biological sensors and elsewhere. A new method of assembling complex colloidal structures in bulk fluid by applying a magnetic field to a mixture of colloidal particles of different size, magnetization and composition is now reported. The shapes that can be obtained when these particles are suspended in a ferromagnetic fluid resemble electric charge distributions such as quadrupoles and octupoles, generating a variety of complex structures including ring- and flower-shaped assemblies. The repulsion that exists between two assembled particles also prevents the formation of clusters.
