The aim of this study is to prepare nanofibers from fullerenes and gold nanoparticles at concentration of (0, 0.4, 1.9 and 3.6) ppm with PAni and PVA, for medical biosensor fabrication using the electrospinning method and to study the effect of both gold nanoparticles and fullerenes on the structural, morphological, XRD and Cyclic Voltammetry properties of nanofibers. The gold nanoparticles are causing pressure in the crystal lattices of the carbon materials (C₈₀, C₇₀, and C₆₀ polymers), Also These systematic displacements are not due to mere physical mixing, but rather are conclusive evidence of a real interaction at the atomic/crystal scale between gold and carbon , nanofibers with sizes ranging from 21.99 nm to 80.5 nm appeared, as did small, the sensor based on AuNP/CNF/PAni/PVA on a gold electrode exhibits a clear dose – dependent electrochemical response, this medical biosensor capable of reliably detecting CA II in the 0-125 ng/ml range.
