AB  - A sensitive simultaneous electroanalysis of phytohormones indole-3-acetic acid 
      (IAA) and salicylic acid (SA) based on a novel copper nanoparticles-chitosan 
      film-carbon nanoparticles-multiwalled carbon nanotubes (CuNPs-CSF-CNPs-MWCNTs) 
      composite was reported. CNPs were prepared by hydrothermal reaction of chitosan. 
      Then the CuNPs-CSF-CNPs-MWCNTs composite was facilely prepared by one-step 
      co-electrodeposition of CuNPs and CNPs fixed chitosan residues on modified 
      electrode. Scanning electron microscope (SEM), transmission electron microscopy 
      (TEM), selected area electron diffraction (SAED), energy dispersive spectroscopy 
      (EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), 
      cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and linear 
      sweep voltammetry (LSV) were used to characterize the properties of the 
      composite. Under optimal conditions, the composite modified electrode had a good 
      linear relationship with IAA in the range of 0.01-50 muM, and a good linear 
      relationship with SA in the range of 4-30 muM. The detection limits were 0.0086 muM 
      and 0.7 muM (S/N = 3), respectively. In addition, the sensor could also be used 
      for the simultaneous detection of IAA and SA in real leaf samples with 
      satisfactory recovery.
