摘要

Referring to the Roman god depicted with two heads, Janus particles are micro- or nano-objects that exhibit different chemistry or polarity on two opposite sides. This makes them a unique class of materials showing interesting properties. They have received increasing attention from the scientific community, since they can be used for a large variety of applications, ranging from catalysis'5' to medical therapy. So far the great majority of methods developed for the generation of such objects break the symmetry by using interfaces or surfaces. This makes the preparation of large quantities rather difficult, because those techniques usually lead only to monolayer equivalents of objects, as the modification occurs in a two-dimensional (2D) reaction space.
