Scanning electron micrographs of the silica particles formed by R5/P_i – and synSil‐1A₁/LCPA‐based assemblies. a,b) Porous, amorphous silica material yielded by precipitation with R5 in the presence of 11.8 mM P_i. c,d) budded spherical silica particles, yielded by precipitation with R5 in the presence of 50 mM P_i. e,f) spherical silica particles yielded by precipitation with synSil‐1A₁/LCPA (10:1). g,h) spherical silica particles yielded by precipitation with synSil‐1A₁/LCPA (1:1), resulting in larger spheres than for synSil‐1A₁/LCPA (10:1).
