Examples of discrete segment and droplet microreactors for the synthesis of nonspherical silica. (A) Experimental set-up for the synthesis of anisotropic silica rod particles. Reproduced with permission from ref.83. (B) Generation of nonspherical colloidosome from W/O/W double emulsions with multiple internal aqueous drops using a glass capillary microfluidic channel. Reproduced with permission from ref.86. (C) Template-free formation of monodisperse doughnut-shaped silica microparticles by droplet-based microfluidics. Reproduced with permission from ref.94. (D) Microfluidic synthesis of monodisperse hierarchical silica particles with raspberry-like morphology. Reproduced with permission from ref.107.
