Schematic workflow diagram for lithographic synthesis of hydrogel colloids, illustrated here for imprint lithography (left), photolithography (center), and flow lithography (right). (I) The patterned template is prepared. (II) The fluid reservoir is filled with a hydrogel pre-cursor fluid(s). (III) Hydrogel colloids are synthesized by simultaneous pattern transfer and cross-linking reaction. (IV) Particles are recovered from the fluid reservoir.
