AB  - The cost-effective synthesis of novel functional nanomaterials has received 
      significant attention in the physical and chemical sciences due to their improved 
      surface area, high catalytic activity along with unique morphological features. 
      This paper reports a facile and eco-friendly synthesis of spindle-like palladium 
      nanostructures (PdSPs) on graphene oxide-cellulose microfiber (GO-CMF) composite 
      for the first time. The GO-CMF/PdSPs composite was synthesized by an 
      electrochemical method without the use of additional surfactants and capping 
      agents. The synthesized materials were characterized and confirmed by using 
      transmission electron microscopy, high-resolution scanning electron microscopy, 
      X-ray diffraction spectroscopy, Raman spectroscopy and Fourier-transform infrared 
      spectroscopy. As-synthesized GO-CMF/PdSPs composite modified electrode was used 
      as a selective electrocatalyst for the oxidation of dopamine (DA). The 
      electrochemical redox behaviors of DA were investigated using cyclic voltammetry 
      (CV). The CV results revealed that the GO-CMF/PdSPs composite modified electrode 
      has 10 folds enhanced oxidation current response to DA than GO, PdSPs and GO-CMF 
      modified GCEs. Under optimized conditions, the GO-CMF/PdSPs composite sensor 
      exhibits a linear response to DA in the concentration range from 0.3 to 196.3 muM 
      with the lower detection limit of 23 nM. The nanocomposite electrode also shows 
      promising features towards the reliable and selective detection of DA, which 
      includes high stability, reproducibility and high selectivity towards the 
      commonly interfering species such as ascorbic acid, uric acid, and 
      dihydroxybenzene isomers. The sensor was successfully tested for the real-time 
      detection of DA in the commercial DA injections and human serum samples.
