Creation of novel colloidal mesostructures with a non-thermal fluctuation

We study the aggregation of amphiphilic colloidal particles in the mixture with water and oil. The particle has hydrophilic and -phobic hemispheres and its diameter is a few micrometers. As the result, the aggregation is qualitatively similar to soap molecules, whereas the aggregate structure is frozen and clearly reflects the anisotropic structure of the particle because of the stiffness of the particle. In addition, we succeeded in covering metal particles with dielectric material by using colloidal particles with metal and dielectric hemispheres.
