It takes two different functional additives to produce the title structures. The proposed mechanism based on the nonclassical particle‐mediated crystallization of calcium carbonate demonstrates the individual and cooperative effects of the polymer poly(sodium 4‐styrenesulfonate) and small folic acid molecules on the formation of heterostructures at different reaction stages.
