A Glucose Biosensor Based on Glucose Oxidase enzyme and ZnO Nanoparticles Modified Carbon Paste Electrode

Abstract: In this study, modified carbon paste electrode (CPE) with zinc oxide (ZnO) nanoparticles used for designing a glucose oxidase enzymatic biosensor to investigation of its electrochemical behavior, and determination of glucose concentration. The size and morphology of synthesized ZnO metal oxide nanoparticles evaluated via chemistry technique like scanning electron microscopy (SEM) and X-ray diffraction (XRD). A pair of clear and stable peaks in PBS ( 0.1 M, pH = 7) obtained for the direct transfer of electrons … Show more

“…However, the accuracy of the system at that resolution is low. Biosensors based on other types of platforms, for example, screen-printed electrodes [18] and bulk electrodes (CPE [19][20][21] or GCE [22,23]) are also being researched to detect glucose.…”

“…In biosensor applications of carbon paste, which is mainly composed of graphite powder and binder, both the composition of the paste and the CPE surface are modified in various ways. For this purpose, while preparing carbon paste metal or nanometal oxide (Svobodová et al, 2012;Comba et al, 2010), carbonnanotube (Anik & Çevik 2009;Li et al., 2012) or modification with metallic structures (Meng-Qin et al, 2007;Amiri et al, 2012;Shamsazar et al, 2016) are among the common applications. In addition to these materials, polymeric structures are also suitable composites for immobilization of biological materials (Donmez, 2020;Sadeghi et al, 2015).…”

“…Various glucose biosensors have been prepared previously with chemically synthesized ZnO nanoparticles [21][22][23]; only limited investigations have focused on glucose biosensors prepared with green synthesized ZnO nanoparticles. The present work describes, the green synthesis of ZnO nanoparticles using Zingiber officinale root extract and the use of these nanoparticles to fabricate a glucose biosensor.…”
