dc.description.abstract | Biointerfaces capable of biological recognition and specificity are very important for the development of carbon nanotube based biosensors. Here, we explore experimentally the effects of O-2 plasma treatment on the biomolecule immobilization properties of single-walled carbon nanotube (SWCNT) electrodes for electrochemical biosensing. The SWCNT film was integrated into an electrochemical three-electrode system on a glass substrate and then treated with an O-2 plasma to improve its electrochemical response. Glucose oxidases, antibodies, and deoxyribonucleic acids (DNAs) were covalently immobilized on the plasma-functionalized (pf) SWCNT working electrodes, and the electrochemical and bioelectrocatalytic properties of three biomolecular assemblies generated on the pf-SWCNT electrodes were investigated using cyclic voltammetry, square-wave voltammetry, and chronoamperometry. The pf-SWCNT films were found to provide electrochemical biosensing electrodes having high electroactivity and sensitivity for detecting glucoses, antigens, and DNA molecules. | - |
