Application of biosynthesized ZnO nanoparticles on an electrochemical H 2 O 2 biosensor

Abstract

ZnO nanoparticles (NPs) were synthesized via a green biochemical method using Corymbia citriodora leaf extract as a reducing and stabilizing agent. The biosynthesized ZnO NPs were characterized by SEM and XRD. An electrochemical H 2 O 2 biosensor was fabricated by modification of a glassy carbon electrode using our proposed ZnO NPs. The electrochemical sensor showed excellent detection performance towards trace amounts of H 2 O 2 , demonstrating that it could potentially be used in clinical applications.Uniterms: H 2 O 2/ electrochemical biosensor.

Synthesis of graphene/DPA composite for determination of nicotine in tobacco products

“…As shown in the Fig. 3A , The IR spectrum of GO presents peaks at 1732, 1622, 1395 and 1049 cm −1 , which are assigned to the C = O stretching of COOH groups, C = O stretching vibration, C — OH stretching vibration and C — O vibrations from alkoxy groups 32 – 34 , respectively. After CV reduction, the intensity of these peaks becomes much less, indicating that the amount of oxygen-containing groups at the surface of GO is greatly reduced.…”
