abstract = "PtAu bimetallic nanoparticles (NPs) were successfully synthesized on single-stranded DNA functionalized graphene nanomaterials (ss-DNA/GR) via a simple chemical reduction method. The nanocomposites (PtAu/ss-DNA/GR) were characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectrometer (EDS) and electrochemical techniques. Then a sensitive dopamine (DA) sensor was fabricated based on PtAu/ss-DNA/GR nanocomposites modified glassy carbon electrode (GCE). The results of electrochemical experiments demonstrated that the sensor exhibited excellent electrocatalytic activity to the oxidation of DA. The sensor displayed wide linear detection range from 8.0×10-8 to 1.0×10-5 M and 1.0×10-5 to 5.0×10-5 M and a low detection limit of 1.0×10-8 M (S/N = 3). In addition, the sensor also showed high selectivity, good reproducibility and stability for DA detection. Thus, it is considered to be an ideal candidate for practical application.",
