We review recent developments on the preparation of multiple emulsions and their applications as templates for material fabrication. Emphasis is placed on microfluidic methods for accurate control of size and morphology and on new formulations that go beyond traditional surfactant systems for increased complexity. The straightforward applicability of multiple emulsions in the fabrication of multihollow particles or capsules of various materials is illustrated through representative examples.
