An electrochemical sensing platform based on zirconium UiO 66 metal-organic framework for determination of vanillin in the presence of folic acid (opens in new tab)

In this study, we developed graphite screen-printed electrodes (GSPEs) modified with zirconium UiO-66 metal-organic framework (Zr-UiO-66 MOF) for the detection of vanillin (VN) and folic acid (FA). Zr-UiO-66 MOF was synthesized via a solvothermal method and used to modify the GSPEs to enhance the sensor sensitivity. Cyclic voltammetry (CV) was employed to investigate the electrochemical properties of the modified GSPEs in a VN solution. The results demonstrated the successful modification of ...
