Platinum is one of the most researched noble metals. It is used in laboratory equipment, electrical contacts, the chemical industry, and jewelry; however,  the high cost of platinum remains a challenge that demands its efficient commercial usage, and the manipulation of its size and shape at the nanoscale can contribute to lowering Pt usage and achieving cost reduction1. In the fields of modern medicine and environmental control, the use of bio sensors for detecting low levels of analytes in a system is important,  and it has been reported that the use of sensor devices integrated by platinum nanowires  provides high sensitivity, improves the signal-to-noise ratio (S/N), and decreases the analytes detection limit2. Furthermore, platinum nanowires could play an important role as both interconnection elements and as active components for the production of nanoscale electronics. Nanowires, by virtue of their size and structural one-dimensionality, could permit the electrons to exhibit quantum confinement effects laterally and enabling new functionalities and device concepts1,3,4. Unfortunately, the progress in the utilization of platinum nanowires has been relatively slow, due to difficulties in developing synthesis procedures that promote well-controlled size, phase purity, crystallinity, and chemical composition. The development of such synthetic methods for generating nanostructures is important and should provide simultaneous control over dimensions, morphology (or shape), and monodispersity (or uniformity).
