MOF’s (Metal Organic Frameworks) consist on a metal ion coordinated to an organic ligand to form structures. They tend to have good chemical stability and different properties that depend on their chemical structure, metal ion and chelating molecules. In this study, we used aniline and pyrrole as organic ligands, and nickel acetate tetrahydrate as the metal ion to synthesize the MOF’s. After synthesizing the precursors for our polymeric material, we continued to test different conditions to electropolymerize them. The process used to electropolymerize the MOF on the surface of the microelectrodes was cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) was used to study their electrochemical properties. The characterization of the MOF-based conductive polymers was carried out in Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), and scanning electron microscope (SEM). The purpose of this research is to modify the surface of carbon fiber microelectrodes with conductive polymers to impart them with different physical and chemical properties. These surface changes will allow us to develop microelectrodes capable of detecting different biomolecules with higher sensitivity
