Microparticle stoichiometry affects granularity of printed objects. (A) Schematic shows how small, green microparticles were mixed with large, red microparticles bearing complementary DNA. (B) Simulation of nucleation events as a function of the number fraction of small microparticles. (C) Schematic shows large and small microparticles assembled within a carrier gel and sectioned for fluorescence microscopy. (D, E) Fluorescence micrographs show the structures resulting from different fractions of small microparticles. Scale bar is 100 μm.
