| Abstract Scope |
Nowadays, designing of more sensitive and selective sensors has been received enormous attentions. Carbon-based nanomaterials are extremely attractive for electrode design as they have high surface area, acceptable biocompatibility, and good electrical conductivity. This work describes fabrication and working of non-enzymatic glucose biosensors based on carbon nano-structures, prepared by pyrolysis method at 600-750oC using easily available biogenic raw materials like potato and bamboo. Synthesized carbon nanomaterials were purified, functionalized, and then characterized by SEM, TEM, XRD etc. Screen printed electrodes were fabricated on Teflon material using functionalized carbon nanoparticles and the resulting non enzymatic biosensors exhibit a good response to glucose detection with a wide linear range from 10−2 to 10−6 M glucose with correlation coefficient (R2 ~0.9978). Both the electrodes showed high sensitivity, selectivity, strong stability and good reproducibility towards glucose in presence of 0.001M H2SO4. |
