Abstract

In this study, an effective electrochemical Sensor for the rapid measurement of L-cysteine based on Glassy carbon electrode modified with Polyindole/Silver nanoparticles nanocomposite is presented. Polyindole nanofibers were synthesized by cyclic voltammetry method at the Glassy carbon electrode surface, and then Silver nanoparticles were deposited on these nanofibers using a constant potential method. Surface morphology and characterization of the modified electrodes were confirmed by field emission scanning microscopy (FE-SEM), X-ray diffraction (XRD), Raman, and FT-IR spectroscopies. The electrochemical investigation showed that the Polyindole/ Silver nanoparticles had very good efficiency with respect to the electrocatalytic oxidation of L-cysteine in phosphate buffer solution (pH = 7. 0). The response of the Glassy carbon electrode/ Polyindole/Silver nanoparticles to L-cysteine was linear in the concentration range of 0. 01-10 mM. The detection limit was obtained at signal/noise=3, 5. 7 μ M. In addition, the Sensor showed good stability and repeatability. The application of the proposed Sensor for the analysis of L-cysteine in human serum was successful.
