Facile Shape-Controlled Synthesis of Well-Aligned Nanowire Architectures in Binary Aqueous Solution

Nanobouquets: Shuttle‐like fusiform bundles of L‐cysteine–Pb nanowires split and open out to form dandelion‐like flowers with well‐aligned architectures (see image). The synthetic procedure provides an efficient route to the controllable preparation of well‐arranged nanowires and, in a further step, to the formation of hierarchical PbS microstructures.
