Abstract 3D hierarchical superstructures (3DHSs) are key products of nature's evolution and have raised wide interest. However, the preparation 3DHSs composed building blocks with different structures is rarely reported, regulating their structural parameters challenging. Herein, a simple lecithin‐mediated biomineralization approach reported for first time to prepare gold 0D nucleus 1D protruding dendritic spikes. It demonstrated that hydrophobic complex by coordination disulfiram (DSF) share chloroauric acid forming 3DHSs. Under lecithin mediation, reduced form nucleus, followed spike growth through reduction complex. The prepared possess well‐defined morphology length ≈95 nm. Notably, density systematically manipulated from 38.9% 74.3% controlling DSF concentrations. Moreover, diameter regulated 9.2 12.9 nm selecting concentrations tune process. Finite‐difference time‐domain (FDTD) simulations reveal spikes “hot spots”. dense structure endows sound performance in surface‐enhanced Raman scattering (SERS) applications.
