Arc-discharge Carbon Nanotube Fabrication in Solution: Electrochemistry and Voltametric Tests

Arc discharge in a solution was applied to fabricate Carbon Nanotubes, CNTs. The products were then applied to electrochemical nano biosensors. The result of such application was compared with other synthesized CNTs, produced by using other methods. The high purity multi walled CNT synthesized by Arc discharge has shown the best outcome on the electrochemical behavior of glassy carbon electrode; comparing to other samples. The performance leads to a better understanding of its electrochemical reactivity. The results also showed a noticeable influence of CNT characteristics on nanobiosensor. Finally the generic application of CNT and the effect of its structure as well as the purity as a preliminary step toward the application in nano(bio)sensor are discussed
