摘要
Monodisperse magnetic particles are templated from double emulsions formed using sequential flow-focus drop formation. The microfluidic drop formation allows the particles to be formed with high monodispersity and with consistently anisotropic internal structure. This structural anisotropy gives rise to magnetic anisotropy, allowing the particles to be rotated by a magnetic field.
