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.
