A new wet chemical approach is presented for the selective synthesis of silver nanowires based on the assembly of silver nanoparticles covered with a bi-functional thiol. The particles are formed spontaneously upon the addition of trace amounts of the thiol to silver nitrate. Dilution of the particle with water leads to the formation of a clear dispersion of white flakes. The silver nanowires are formed while drying the flakes in air. The silver nanowires are characterized with scanning electron microscopy (SEM) and have aspect ratios of about 46. The results are discussed in the context of an assembly mechanism driven by intermolecular interactions among thiol molecules.
