Fig. 3. Multiphase and cross-scale assembly of architectures with microgels consisting of varied prepolymer solutions, dyes, and particles.

Fig. 3

(A) Microgels crosslinked by different manners on a single electromicrofluidic platform. Left: PEGDA with green particles by photocrosslinking; middle: Matrigel with blue dye by thermal crosslinking; right: polyacrylamide with red particles by chemical crosslinking. (B to G) Postcrosslinking PEGDA microgels, containing random or reorganized encoding particles, assembled (B to D) and stacked (E to G) in liquid PEGDA solution (movie S4). (H and I) Precrosslinking assembly of nine PEGDA droplets with dye or addressable particles to form a PEGDA architecture (3 mm × 3 mm × 100 μm) after crosslinking on light exposure (movie S5). (J and K) Fluorescence microscopy images of the crosslinked and seamless heterogeneous architecture. Scale bars, 1 mm (A to J); 200 μm (K).
