Carbon nanotube (CNT)‐based electrochemical biosensors are used to determine the concentration of analytes by measuring mass, heat, or oxygen. CNTs, as an immobilizing platform of biomaterials, play an important role in enhancing the electron transfer mechanism of a biosensor. The large surface area and optimum aspect ratio (length to thickness) of CNTs maximize the amount of immobilized biomaterials on the surface. In this study, various aspect ratios of CNTs are reported, based on the alteration of growth mechanisms using CVD. The growth‐dependent and ‐independent parameters of the CNT arrays are studied as functions of the synthesis method.
