This review summarizes recent advances in electrochemical biosensors based on carbon nanotubes (CNTs) and carbon nanofibers (CNFs) with an emphasis on applications of CNTs. CNTs and CNFs have unique electric, electrocatalytic and mechanical properties, which make them efficient materials for developing electrochemical biosensors.We discuss functionalizing CNTs for biosensors. We review electrochemical biosensors based on CNTs and their various applications (e.g., measurement of small biological molecules and environmental pollutants, detection of DNA, and immunosensing of disease biomarkers). Moreover, we outline the development of electrochemical biosensors based on CNFs and their applications. Finally, we discuss some future applications of CNTs.

“…Extensive work has been carried out with redox protein films over the past few decades in order to find methods to increase the electron transfer rate between enzyme and electrode [1 8]. For example, a variety of carbonbased materials such as carbon nanotubes (CNTs) [9 11] and carbon nanofi bers (CNFs) [12,13] have been successfully employed for the direct electron transfer of proteins in fi lms. Their properties of hydrophilicity, nontoxicity, excellent film-forming ability, and remarkable biocompatibility offer excellent prospects for biocompatible immobilization matrices and the design of novel biosensors.…”

Myoglobin/gold nanoparticles/carbon spheres 3-D architecture for the fabrication of a novel biosensor

A novel biosensor based on a myoglobin/gold nanoparticles/carbon spheres (Mb AuNPs CNs) 3-D architecture bioconjunction has been fabricated for the determination of hydrogen peroxide (H 2 O 2 ). Cyclic voltammetry (CV), Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) were used to characterize the bioconjunction of the AuNPs CNs with Mb. Experimental results demonstrate that the AuNPs CNs hybrid material is more effective in facilitating electron transfer of the immobilized enzyme than CNs alone, which can be attributed to the unique nanostructure and larger surface area of the bioconjunction. The biosensor displayed good performance for the detection of H 2 O 2 with a wide linear range from 0.28 μmol/L to 116.5 μmol/L and a detection limit of 0.12 μmol/L. The Michaelis-Menten constant K M app value was estimated to be 0.3 mmol/L. The resulting biosensor exhibited fast amperometric response, and good stability, reproducibility, and selectivity to H 2 O 2 .

“…VACNFs were also used for biosensing applications (Baker et al, 2006 b). The use of highly activated CNFs for the preparation of glucose biosensors, in comparison with SWCNT and graphite powder, is presented by Vamvakaki et al, 2006. They demonstrated that CNFs are far superior to carbon nanotubes or graphite powder as matrix for the immobilization of proteins and enzymes and for the development of biosensors.…”
