In the current work, a plant-based carbon sample is synthesized successfully from monkey ladder (EntadaGigas) plant seeds by combustion technique. The prepared samples are subjected to characterizations such as Powder X-ray Diffractogram(PXRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Energy Dispersive X-ray (EDX) Analysis. The PXRD pattern of the prepared MLC carbon sample exhibits the graphitic structure. The SEM micrograph displays the flake-like morphology; the FTIR spectrum reveals the presence of carbon-based functional groups. The dielectric property of the prepared carbon sample has been studied and confirms the good ac conductivity. The cole-cole plot of the prepared MLC carbon sample displays a single semicircle which signifies the highly resistive grain boundaries. The electrochemical study of prepared MLC Coated Ni foam electrode in 0.1 ​M NaOH electrolyte solution showed good redox potential output proposed by cyclic voltammetric and amperometric studies.The developed material exhibited a good response towards the glucose sensor with a sensitivity of 0.8 mAmM-1 and a limit of detection of 0.5 ​mM.
