Abstract: | Uncontrolled glucose level continues to be part of a threat for civilian populations and badly effects quality of the human life all over the world. Biosensors fabricated with nanomaterial promise faster and more efficient alternatives to traditional methods for reliable measurement of glucose. In this study, a sensing film unit on graphite electrodes combining poly{9,9-dioctyl-9H-fluorenealt-5,6-bis(octyloxy)-4,7-di(furan-2-yl)benzo[c][1,2,5]oxadiazole)}(PFBFFL) and single walled carbon nanotubes (SWCNTs) were employed as a transducer surface. To the best of my knowledge, a sensor design that combines both 9,9-dioctyl-9H-fluorene-co-5,6bis(octyloxy)-4,7-di(furan-2-yl)benzo[c][1,2,5]oxadiazole bearing polymer and SWCNTs was attempted for the first time, and used as a glucose sensor. Additionally, the PFBFFL was for the first time used as a sensing layer for glucose detection. The low limit of detection (0.037 mM) and high sensitivity (98.36 mu A mM(-1) cm(-2)) of the biosensor are attributed to the great architecture. This could be confirmed by the very low K-M(app) value, which is evaluated to be only 0.85 mM. The fabricated sensor surface characteristics were characterized by cyclic voltammetry (CV) and scanning electron microscopy (SEM) techniques. The applicability behavior of the sensor was also successfully tested in the beverages. (C) 2019 The Electrochemical Society. |
