PbS nanostructures with various morphologies were successfully fabricated through a biomolecule-assisted method. It was found that the morphology of PbS nanostructures was greatly influenced by the addition of cysteine and the morphology of Pb-cysteine precursor. Dendritic, hierarchical and multi-armed PbS nanostructures were obtained by adjusting the amount of cysteine molecules. These well-defined nanostructures will be essential for the assembly of functional nanodevices. Furthermore, the bio-inspired strategy is quite simple and environmental friendly. As their scalability for mass production is feasible, the extension of this method to other important semiconductor materials will be open for further exploration.
