In the past decade, the use of nanotechnology as a tool to develop novel structures of carbon and metal nanoparticles as well as the fabrication ofdevices for bio-sensinghas increased tremendously. Encouraged by the continuing research work on biosensors using nanomaterials, it was felt to explore some new carbonaceous materials for the synthesis of carbon nanoparticles for their possible application as biosensors. In this context, different types of carbon based nanostructured materials have been synthesized fromeasily available raw materials like coconut oil, bamboo, potato, barley, etc., employing simple processes of burning and pyrolysis. Interestingly, it was found that different type of raw materials produced carbon nanoparticles of different shapes and sizes viz. CCNT, CN, CNA and CNS from coconut oil, bamboo, peeled potatoes and barley, respectively. The non-enzymatic electrochemical behavior of all the electrodes showed good response to glucose detection with a wide linear range from10−2 to 10−6 M.The sensitivity and selectivity of the electrodes towards glucose oxidation promises its effectiveness as a non-enzymatic glucose sensor for practical applications also. The non-enzymatic cholesterol biosensor basedon CCNT, showed a high sensitivity of ~15.31 μAμM−1cm−2 and lower detection limit of 0.017 μM. This research work is still continuing with other carbonaceous materials and the control of the shape and the size of these nanocarbons and their dependency on the mechanism of bio-sensing are under investigation. However, the proposed electrodeshold a great potential for the development of non enzymatic biosensors for real samples.
