Abstract: DOI: 10.24193/subbchem.2020.2.19 Published Online: 2020-06-30 Published Print: 2020-06-30 pp. 233-242 VIEW PDF: FULL PDF ABSTRACT: Flexible screen-printed electrodes on stone paper substrate (HP) and modified with gold nanoparticles (HP-AuNPs) or AuNPs-poly-methylene blue (HP-AuNPs-PMB) were fabricated and morphologically investigated by SEM/EDS. The electrochemical properties of the new electrodes were studied by cyclic voltammetry (CV). The best electrocatalytic properties for uric acid detection were obtained with HP-AuNPs electrode: 0.16 µM Limit of Detection, 5x10-7- 10-4 M linear range and 20.7 mA/M sensitivity. Key words: uric acid detection, stone paper substrate, AuNPs modified electrodes |
