A new method for biomimetic silica fabrication is reported. Organized poly(ethyleneimine) rapidly catalyzes and directs the shape of silica in the hydrolysis of tetramethoxysilane under ambient conditions. The resultant silica displays a diversity of controllable morphologies, such as flower, plate, bundle, leaf, and sphere (see Figure, scale bar represents 1 μm).
