Bifunctional and/or anisometric Janus particles have proven to be superior to spherical and chemically isotropic colloids for a wide range of promising applications, such as in nanorobots, physical sensors, microrheology, drug delivery, magnetic storage, electronic devices, surfactants, and compatibilizers. Nevertheless, large-scale technical applications have been halted by the restricted accessibility of these polar colloids. Established synthesis methods that allow for breaking the symmetry are laborious and expensive.
