In this work, Carbon Nanoparticles (CNPs) were synthesized by one step Laser ablation of natural coconut shell charcoal in ethanol and water media. The HRTEM studies showed that the average particle size was of the order of 29 nm in ethanol with amorphous nature whereas in water, the particle average size was about 15 nm with graphitic structure. Photoluminescence (PL) properties of CNPs formed were studied. CNPs coated Nickel foil electrode (NiFE) was investigated for glucose measurement by cyclic voltammetry (CV) and chronoamperometry. The CNPs exhibited good response to glucose. The sensor was stable, wide range of detection and fabricated simply without use of any kind of binder or enzymes.
