The paper provides insights on the less costly and eco-friendly green technique used for the synthesis of gold metal nanoparticle from banana (Musa paradisiaca) peel extracts. Electrospinning method was used to fabricate a stabilized nanocomposite polyacrylonitrile functionalized with green synthesized gold (PAN/Au) into nanofibers. The nanoparticle and its nanocomposite were characterized by using spectroscopy and surface morphology techniques. Surface characterization techniques like scanning electron microscopy (SEM), transmission electron microscopy (TEM), Particulate Systems Nano-Plus Zeta/Nano Particle Analyser were used to determine the shape and size of the nanoparticles. Spectroscopy characterization was done by using UV–Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), and X-ray diffractometry (XRD), The spectroscopic studies for the gold nanoparticles were conducted at various volumes, concentrations, and synthesis time. The nanoparticle diameters were calculated to be on an average of 9 nm. Shape uniformity, stability and particle size distribution of the nanoparticles and nanocomposite were confirmed by TEM and Zeta Potential study. Furthermore, the nanocomposites of gold nanoparticles doped in polyacrylonitrile nanofibers showed improved electrochemical information as compared to the monometallic nanoparticles, unmodified PAN molecule, and the bare glassy carbon electrode. These properties exhibited by the nanocomposite PAN-Au suggests that it can be used as electrochemical sensors.
