The renewable and low-cost biosensor consisting of graphite pencil counter, reference, and fluorine immobilized on a graphite pencil (FPE) working sensor was explored for use in cyclic voltammetry (CV) and square-wave stripping voltammetry (SW) in cobalt assay. In the voltammetric study, the analytical optimum conditions attained a low detection limit. The results were used for the diagnosis of a frog’s cell cut from its liver. The developed system can be used for organ treatment, biological analysis, and in-vivo diagnostic detection.
