A) A schematic description of a cascade mechanism in which the bistable network that reaches either high or low steady states (Hss and Lss, respectively) regulates nanoparticle formation reaction and growth (NRG) processes and consequently yields variable output in Au NP morphology, self‐assembly, and shape. B) Representative results highlighting bistability in the SS product distribution (manifested by K_app; Table S1), obtained in the reaction shown in (A) for different initial concentration combinations of the peptides (E, N and R; Table 1) and small molecule (S). In all cases, the network reactions were carried out at pH 7, with [E] and [N] kept in equal amounts, and total peptide concentration [N+R] remains constant at 100 μm. Inset: the equation used to calculate the SS constant K_app. ^[3c]
